A charge of 1.6 x 10-10C is placed in a uniform electric field of intensity 2.0 x 105 NC-1. calculate the magnitude of the electric force exerted on the change
A
3.2 x 105N
B
1.8 x 105N
C
3.2 x 10-5N
D
1.8 x 10-5N
Verified Correct Answer: C.
Physical Principles & Numerical Solution
F = Exq = 2.0 x 105 x 1.6 x 10-10
= 3.2 x 10-5N
