Simba remagetsi - matambudziko nemhinduro
1. Kana iyo simba remagetsi risingachinji iri 144 N, daro riri pakati pezvose zviri zviviri nderei? mhosva... (1) μC = 10-6 C uye k = 9.109 Nm2.C-2)
Zvinozivikanwa:
Simba remagetsi (F12) = 144 N
Chaji 1 (q)1) = 10 μC = 10 x 10-6 C
Chaji 2 (q)2) = 4 μC = 4 x 10-6 C
Nguva dzose (k) = 9 X 109 Nm2.C-2
C = Coulomb, N = Newton, m = mita
Zvaidiwa: Daro pakati pemari dzese dziri mbiri (r)
Solution:
Kuenzanisa kwe Mutemo weCoulomb :
F = simba remagetsi risingachinji, k = Coulomb's constant, q = kuchaja kwemagetsi, r = daro pakati pechaja dzese dziri mbiri
Kureba pakati pemari dzese dziri mbiri (r) = 5 x 10-2 mamita = 5 x 10-2 x 102 masendimita = masendimita mashanu.
2. Machaja maviri akaparadzaniswa nedaro re rKana simba remagetsi risingachinji riri 3.6 N, daro riri pakati pemachaji ese ari maviri nderei? (1 μC = 10-6 C uye k = zana9 Nm2.C-2)
Zvinozivikanwa:
Simba remagetsi (F)12) = 3.6 N
Chaji 1 (q)1) = 9 μC = 9 x 10-6 C
Chaji 2 (q)2) = 4 μC = 4 x 10-6 C
Nguva dzose yaCoulomb (k) = 9 X 109 Nm2.C-2
C = Coulomb, N = Newton, m = mita
Zvaidiwa: Daro pakati pemari dzese dziri mbiri (r)
Solution:
Kureba pakati pemari dzese dziri mbiri (r) = 0.3 m = 0.3 x 100 masendimita = masendimita mashanu.
3. Mapoinzi matatu anoshandiswa sezvakaratidzwa mumufananidzo uri pazasi. Simba remagetsi rinomira panzvimbo A rinokura sei? (k = 9.109 Nm2.C-2; 1 μ = 10-6)
Zvinozivikanwa:
murandu A (q)A) = -2 μC = -2 x 10-6 C
murandu B (q)B) = 8 μC = 8 x 10-6 C
murandu C (q)C) = 4,5 μC = 4,5 x 10-6 C
Coulomb's nguva dzose (k) = 9 X 109 Nm2.C-2
Daro riri pakati pemari A neB (rAB) = 4 cm = 4 x 10-2 m
Daro riri pakati pemari A neC (rAC) = 3 cm = 3 x 10-2 m
C = Coulomb, N = Newton, m = mita
Zvaidiwa: Simba remagetsi risingachinji panzvimbo A
Solution:
Kuenzanisa kwemutemo waCoulomb:
F = simba remagetsi risingachinji, k = Coulomb's nguva dzose, q = electric charge, r = daro riri pakati pemari dzese dziri mbiri
Simba remagetsi risingachinji panzvimbo A:
4. Kuchaja kwenzvimbo nhatu sezvakaratidzwa mumufananidzo uri pazasi. Simba reCoulomb rakaonekwa neCharge B rakakura sei? (k = 9.109 Nm2.C-2; 1 μC = 10-6 C).
Zvinozivikanwa:
qA = 10 µC = 10 x 10-6 C = zana-5 Coulomb
qB = 10 µC = 10 x 10-6 = 10-5 Coulomb
qC = 20 µC = 20 x 10-6 = 2 x gumi-5 Coulomb
rAB = 0.1 mamita = 10-1 m
rBC = 0.1 mamita = 10-1 m
k = 9 x 109 Nm2C-2
Zvaidiwa: Simba reCoulomb rakaonekwa neCharge B
Solution:
Kune mauto maviri eCoulomb anobata basa paB, simba reCoulomb pakati pemhosva A neB (F)AB) uye simba reCoulomb pakati pemhosva B naC (F)BC). Simba reCoulomb rinoonekwa nechaji B isimba rechokwadi reFAB uye FBC.
Simba reCoulomb pakati pemhosva A neB:
Mari A yakasainwa zvakanaka uye mari B yakasainwa zvakanaka kuitira kuti FAB mapoinzi ekuchaja C.
Simba reCoulomb pakati pemhosva B naC:
Mutongo B wakasainwa zvakanaka uye mutongo C wakasainwa zvakanaka zvekuti FBC mapoinzi ekubhadharisa A.
Simba reCoulomb rinoonekwa nechaji B:
FB =FBC - FAB = 180 – 90 = 90 N
Simba reCoulomb rinowanikwa nechaji B (F)B) ndi90 Newtons. Kutungamira kwaFB zvakafanana nekwakananga kwaFBC mapoinzi ekubhadharisa A.
5Sarudza hukuru uye gwara reCoulomb force pachaji B (k = 9 x 109 Nm2C-2, 1 μC = 10-6 C).
Zvinozivikanwa:
murandu A (q)A) = +Q
murandu B (q)B) = -2Q
murandu C (q)C) = -Q
Daro riri pakati pemari A neB (rAB) = r
Daro riri pakati pemari B neC (rBC) = 2r
k = 9 x 109 Nm2C-2
Zvaidiwa: Hukuru uye kutungamira kweCoulomb force iri pacharge B
Solution:
Simba reCoulomb pakati pemhosva A neB:
Chaji A iri positive uye chaji B iri negative saka ndiyo nzira yairi kuenda FAB mapoinzi ekubhadharisa A.
Simba reCoulomb pakati pechaji B nechaji C:
Chaji B iri negative uye chaji C iri negative saka ndiyo nzira yaFBC mapoinzi ekubhadharisa A.
Mutemo weNet Force pamhosva B:
F = FAB +FBC = 2 k Q2/r2 + 0.5 k Q2/r2 = 2.5 k Q2/r2 = 2.5 k Q2 r-2
Kutungamira kwenzvimbo dzekumanikidza kuenda kuA kana kuruboshwe.
