1. Tsvaga simba remagetsi panzvimbo iri pa1 cm kubva pakuchaja 5.0 μ C. Coulomb constant (k) = 9 x 10 9 Nm 2 C −2 , 1 μC = 10 −6 C.
Zvinozivikanwa:
Nhambwe kubva pakuchaja (r) = 1 cm = 1/100 m = 0.01 m = 10 -2 m
Chaji (q) = 5.0 μ C = 5.0 x 10 -6 C
Chimiro cheCoulomb (k) = 9 x 10 9 Nm 2 C −2
Zvinodiwa: Simba remagetsi (V)
Solution:
Kugona kwemagetsi:
Simba remagetsi i4.5 x 10 6 Volts

2. murandu Q1 = 5.0 μC uye kuchaja Q2 = 6.0 μC. Nguva dzose yaCoulomb (k) = 9 x 109 Nm2C-2, 1 μC = 10-6 C. Poindi A iri pakati pemhosva. Sarudza simba remagetsi panzvimbo A.
Zvinozivikanwa:
Chaji Q 1 = -5.0 μ C = -5.0 x 10 -6 C
Kureba kwenzvimbo A kubva paQ 1 = 10 cm = 0.1 m = 10 -1 m
Chaji Q 2 = 6.0 μ C = 6.0 x 10 -6 C
Kureba kwenzvimbo a kubva kuQ 2 = 10 cm = 0.1 m = 10 -1 m
Nguva dzose yaCoulomb (k) = 9 x 10 9 Nm 2 C −2
Zvinodiwa: Simba remagetsi panzvimbo A
Solution:
Simba remagetsi 1 :
Simba remagetsi 2 :
Simba remagetsi panzvimbo A :
V = V 2 – V 1
V = (54 - 45) x 10 4
V = 9 x 10 4

3. murandu q1 = 5.0 μC uye kuchaja q2 = 6.0 μC. Nguva dzose yaCoulomb (k) = 9 x 109 Nm2C-2, 1 μC = 10-6 C. Sarudza simba remagetsi panzvimbo A.
Zvinozivikanwa:
Chaji Q 1 = -5.0 μ C = -5.0 x 10 -6 C
Kureba kwenzvimbo A kubva kuQ 1 = 40 cm = 0.4 m = 4 x 10 -1 m
Chaji Q 2 = 6.0 μ C = 6.0 x 10 -6 C
Kureba kwenzvimbo A kubva kuQ 2 = 50 cm = 0.5 m = 5 x 10 -1 m
Nguva dzose yaCoulomb (k) = 9 x 10 9 Nm 2 C −2
Zvinodiwa: Simba remagetsi panzvimbo A
Solution:
Simba remagetsi 1 :
Simba remagetsi 2 :
Simba remagetsi panzvimbo A :
V = V 1 + V 2
V = (-11.25 + 10.8) x 10 4
V = -0.45 x 10 4
V = -4.5 x 10 3
Simba remagetsi panzvimbo A i -4.5 x 10 3 Volts
