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

Options:

Answer:

Solution:

$A \equiv (- a, 0, 0) B \equiv (0, a, 0)$ Point charge is moved from $A$ to $B$ $V_{A} W = V_{B} = 0 = 0$ $∴ W = 0$ or the correct option is (c).
