Electrostatics 2 Question 11

12. Positive and negative point charges of equal magnitude are kept at (0,0,a/2) and (0,0,a/2), respectively. The work done by the electric field when another positive point charge in moved from (a,0,0) to (0,a,0) is

(2007,3M)

(a) positive

(b) negative

(c) zero

(d) depends on the path connecting the initial and final positions

Show Answer

Answer:

Correct Answer: 12. (c)

Solution:

  1. A(a,0,0),B(0,a,0)

Point charge is moved from A to B

VA=VB=0W=0

or the correct option is (c).
