Problem
Positive and negative point charges of equal magnitude are kept at (0,0,2a) and (0,0,−2a) respectively. The work done by the electric field when another positive point charge is moved from (−a,0,0) to (0,a,0) is
(1) positive
(2) negative
(3) zero
(4) depends on the path connecting the initial and final positions
