The diagram shows a uniform electric field in which the lines of equal potential are spaced 2.0 cm apart. What is the value of the electric force which is exerted on a charge of +5.0 µC when placed in the field?
A
6.0 × 10–6 N
B
1.5 × 10–2 N
C
3.0 × 103 N
D
6.0 × 108 N
Answer
1.5 × 10–2 N
Explanation
Solution
E = 
= 3000 V/m
F = 9E = 1.5 × 10–2 N
