7. Anya dị n'etiti iberibe ígwè abụọ yiri ibe ha bụ 0,2 cm. A na-enye iberibe ígwè abụọ ahụ ọkụ eletrik megide ibe ha ruo mgbe ọdịiche nwere ike iru volt 20.000. Chajị elektrọn bụ 1,6 × 10 –19 C. Oke na ntụziaka nke ike Coulomb na elektrọn n'etiti iberibe ígwè abụọ bụ...
A. 0,80 × 10-12 N, elu
B. 1,20 × 10-12 N, ala
C. 1,20 × 10-12 N, elu
D. 1,62 × 10-12 N, ala
E. 1,62 × 10-12 N, elu
Mkparịta ụka:
A maara :
d = 0,2 cm = 0,002 m
V = Volt 20.000
e = 1,62 x 10-19 C
A jụrụ :
Ike eletriki (F)?
Jawab :
Usoro maka ubi eletriki, voltaji na anya dị n'etiti efere :
E = V / d
Nkọwa: E = ubi eletriki, V = voltaji, d = anya dị n'etiti efere
Usoro ike Coulomb, ubi eletrik na chajị :
F = q E
Nkọwa: F = Ike Coulomb ma ọ bụ ike eletrik, q = chajị, E = ubi eletrik
Ibu na ntụziaka nke ike Coulomb na elektrọn :
F = q E = q V / d
F = (1,62 x 10-19 C)(20.000 V) / 0,002 m
F = 1,62 x 10-12 N
Electron na-enweta ike na-adịghị mma, ya mere efere na-adịghị mma na-achụpụ ha ma efere dị mma na-adọta ha. Ya mere, ebe ike ahụ na-aga elu.
Azịza ziri ezi bụ E.
