Q. Positive and negative point charges of equal magnitude are kept at $ ( 0, 0, \frac{a}{2}) $ and $ ( 0, 0, \frac{-a}{2}) $ respectively. The work done by the electric field when another positive point charge is moved from $ ( -a, 0, 0) $ to $ (0, a, 0) $ is

Solution:

$A \equiv(-a, 0,0)$
$B \equiv(0, a, 0)$

Point charge is moved from $A$ to $B$
$V_{A}=V_{B}=0$
$\therefore W=0$
