Simba remagetsi pa kondakita yebhora - matambudziko nemhinduro
1. Muchina wekutamba bhora une 4-μC une dhayamita ye8-cm. Tsvaga simba remagetsi pamusoro pebhora. (k = 9.10 9 Nm 2 .C -2 )
Zvinozivikanwa:
The electric charge (Q) = 4 μC = 4 x 10-6 C 
Radiyo yebhora (r) = 8 cm = 8 x 10 -2 m
Chimiro cheCoulomb (k) = 9.10 9 Nm 2 .C -2
Zvinodiwa: Simba remagetsi pamusoro pebhora (V)
Solution:
V = k Q / r
V = (9 x 10 9 )(4 x 10 -6 ) / (8 x 10 -2 )
V = (36 x 10 3 ) / (8 x 10 -2 )
V = (36/8) x 10 3 x 10 2
V = 4.5 x 10 5 Volt
2. Kondakita yakatenderera ine dhayamita ye3 -cm (1 μC = 10 -6 C uye k = 9.10 9 Nm 2 .C -2 ). Kana kondakita yakachajwa zvakanaka +1 μC saka simba remagetsi panzvimbo A ndiro …
Solution:
Simba remagetsi riri mukati memuchina wesimbi = Simba remagetsi riri pamusoro pemuchina wesimbi.
Zvinozivikanwa:
Chaja yemagetsi (Q) = 1 μC = 1 x 10-6 C 
Radiyo yemutyairi wedenderedzwa (r) = 3 cm = 3 x 10 -2 m
Chimiro cheCoulomb (k) = 9.10 9 Nm 2 .C -2
Zvinodiwa: Simba remagetsi panzvimbo A (V)
Solution:
V = k Q / r
V = (9 x 10 9 )(1 x 10 -6 ) / (3 x 10 -2 )
V = (9 x 10 3 ) / (3 x 10 -2 )
V = (9/3) x 10 3 x 10 2
V = 3 x 10 5 Volt
3. Bhora resimbi risina chinhu rine radius ye9 -cm rine charge yemagetsi yeCoulomb ye6.4 x 10 -9 , sezvakaratidzwa mumufananidzo uri pazasi. Daro riri pakati pepoindi O nepoindi P = 4 cm; Daro riri pakati pepoindi P nepoindi Q = 5 cm; Daro riri pakati pepoindi Q nepoindi R = 18 cm uye k = 9.10 9 Nm 2 .C -2 . Sarudza simba remagetsi papoindi P.
mhinduro
Simba remagetsi riri mukati memuchina wesimbi = Simba remagetsi riri pamusoro pemuchina wesimbi.
Zvinozivikanwa:
Chaja yemagetsi (Q) = 6.4 x 10-9 C
Radiyo yemutyairi wedenderedzwa (r) = OP + PQ = 4 cm + 5 cm = 9 cm = 9 x 10 -2 m
Chimiro cheCoulomb (k) = 9.10 9 Nm 2 .C -2
Zvinodiwa: Simba remagetsi panzvimbo P (V)
Solution:
V = k Q / r
V = (9 x 10 9 )(6,4 x 10 -9 ) / (9 x 10 -2 )
V = 10 9 (6,4 x 10 -9 ) / 10 -2
V = 6.4 / 10 -2
V = 6.4 x 10 2
V = 6.4 x 100
V = 640 Volt
1. Mubvunzo: Chii chinonzi simba remagetsi?
Mhinduro: Simba remagetsi (electric potential energy) isimba remagetsi rinoonekwa pachaji imwe neimwe panzvimbo chaiyo.
2. Mubvunzo: Simba remagetsi riri pamusoro pebhora rinofambisa magetsi rinoonekwa sei?
Mhinduro: Simba remagetsi riri pamusoro pebhora rinofambisa magetsi rakafanana uye rinopihwa nefomula V = kQ/R, apo Q ndiyo chaji iri pabhora uye R ndiyo radius yaro.
3. Mubvunzo: Sei simba remagetsi risingachinji kwese kwese pamusoro pebhora rinofambisa magetsi rakachajwa?
Mhinduro: Maconductor ari mu electrostatic equilibrium ane simba remagetsi rakamira pamusoro. Saka, hapana basa rinoitwa pakufambisa chaji pamusoro, zvichiita kuti simba rirambe riripo.
4. Mubvunzo: Mukana wekutamba unosiyana sei mukati mebhora rinofambisa bhora?
Mhinduro: Mukati mebhora rinofambisa magetsi rakachajwa zvakaenzana, simba remagetsi rinosiyana, asi kana riri bhora rinofambisa magetsi risina chinhu, simba rinoramba riri mukati uye rakaenzana nesimba riri pamusoro paro.
5. Mubvunzo: Saizi yebhora rinofambisa mhepo inokanganisa sei kugona kwaro pamusoro, tichifunga nezvekuchaja kwaro nguva dzose?
Mhinduro: Bhora rakakura (R rakakura) rinenge riine mukana mudiki wepamusoro weQ yekuchaja, zvichibva pafomura V = kQ/R.
6. Mubvunzo: Simba remagetsi rine chekuita sei nemagetsi?
Mhinduro: Simba remagetsi nesimba remagetsi zvine hukama ne equation E = -dV/dr, apo dV iri shanduko musimba uye dr iri shanduko munzvimbo.
7. Mubvunzo: Sei tisingakwanise kuva nemunda wemagetsi mukati mebhora rinofambisa magetsi mu electrostatic equilibrium?
Mhinduro: Maerekitironi ari muconductor anofamba kusvika adzima chero minda yemagetsi yekunze. Kana yasvika pakuenzana, munda wemagetsi uri mukati meconductor unova zero.
8. Mubvunzo: Chii chingaitika kumagetsi ebhora rinofambisa magetsi kana huwandu hwechaji pariri hwakapetwa kaviri?
Mhinduro: Kupeta kaviri chaji Q kwaizopeta kaviri simba remagetsi V, tichifunga nezvehukama hwaV = kQ/R.
9. Mubvunzo: Chii chinorehwa neshoko rekuti 'k' muchimiro chemagetsi ane simba?
Mhinduro: 'k' ishoko raCoulomb risingachinji, iro rinenge 8.99 x 10⁹ N.m²/C² mu vacuum.
10. Mubvunzo: Simba remagetsi rinosiyana sei nesimba remagetsi?
Mhinduro: Simba remagetsi (electrical potential energy) isimba rinotengeswa nekuda kwenzvimbo yaro mumunda wemagetsi, nepo simba remagetsi (electrical potential energy) isimba remagetsi pamutengo weyuniti.
11. Mubvunzo: Bhora rinofambisa magetsi rine chaji rinokanganisa here kugona kwemagetsi kwezvinhu zviri pedyo?
Mhinduro: Ehe, chero chinhu chakachajwa chinogadzira munda wemagetsi munzvimbo yacho, izvo zvinokanganisa kugona kwemagetsi kwezvinhu zviri pedyo.
12. Mubvunzo: Simba remagetsi riri pedyo nebhora rinofambisa magetsi rinoverengwa sei?
Mhinduro: Inoverengwa uchishandisa fomura V = kQ/r, apo r iri chinhambwe kubva pakati pebhora kusvika padonho.
13. Mubvunzo: Kana mabhora maviri akafanana ekutungamirira, rimwe rakachajwa nerimwe risina kuchajwa, akabatana obva aparadzaniswa, chii chinoitika kune simba rerimwe nerimwe?
Mhinduro: Kuchaja kuchagovaniswa zvakaenzana pakati pemabhora maviri, zvichiita kuti potentials dzavo dzifanane.
14. Mubvunzo: Ndeipi basa rekugadzirisa bhora rinofambisa bhora pasi?
Mhinduro: Kuisa pasi kondakita kunoita kuti ikwanise kuchinjana chaji nePasi kusvika simba rayo rava zero.
15. Mubvunzo: Sei simba remagetsi riri zero mukati mebhora rinofambisa magetsi riri pasi?
Mhinduro: Kana yamiswa, kondakita anochinjana machaji nePasi kusvika simba remagetsi riri mukati maro rapera, zvichiita kuti pave ne zero.
16. Mubvunzo: Chimiro chemuchina wekufambisa mhepo chinokanganisa kugona kwawo pamusoro here?
Mhinduro: Pakuchaja kwakapihwa, kugoverwa kunogona kusiyana zvichienderana nechimiro, asi mukuenzana kwemagetsi, mukana unoramba uripo pamusoro pechero kondakita.
17. Mubvunzo: Kugoverwa kwemari kunosiyana sei pa kondakita isiri denderedzwa?
Mhinduro: Pamuchina usingatenderere, chaji inowanzo ungana panzvimbo dzakapinza kana kuti pamipendero nekuda kwekuwanda kwetambo dzemagetsi.
18. Mubvunzo: Sei shiri dzichigona kugara patambo dzemagetsi dzine simba guru dzisingabatwe nemagetsi?
Mhinduro: Shiri hadzibatwe nemagetsi nekuti hadzisi kupedza circuit. Simba remagetsi rinoramba riripo mumuviri wadzo wese sezvo dzichingobata waya imwe chete, saka hapana musiyano uripo.
19. Mubvunzo: Kuvapo kwechinhu che dielectric pedyo nebhora rinofambisa magetsi rinochajwa kunokanganisa sei kugona kwaro kwemagetsi?
Mhinduro: Chinhu che dielectric chinokanganisa simba remagetsi riri pedyo ne conductor, izvo zvinogona kukanganisa simba remagetsi. Kazhinji, dielectrics inoderedza simba remagetsi rinoshanda.
20. Mubvunzo: Ndeipi simba remagetsi riri panzvimbo iri kure zvikuru nebhora rinofambisa magetsi rakachajwa?
Mhinduro: Simba remagetsi rinosvika zero kana munhu achifamba kure nekwakachajwa.
Kunzwisisa hunhu hwesimba remagetsi, kunyanya nemaconductor akaita semabhora, kunopa ruzivo rwezviitiko zvakawanda mu electrostatics uye mashandisirwo chaiwo.
