Poistive 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 poistive point charge is moved from `(-a, 0, 0)` to `(0, a, 0)` isA. positiveB. negativeC. zeroD. depends on the path connecting the initial and final positions

Answer» Correct Answer - C
The two charge an electric dippole. The points (- a, 0, 0, ) and ( 0, a, 0 ) are at the same distance from the positive and negative charges of equal magnitud Hence the leectric potential si zero at these poits. Hence the work done is zero.
