Question

A charge (-9) and another charge (+Q) are kept at two
points A and Brespectively. Keeping the charge (+Q) fixed
at B, the charge (-9) at A is moved to another point C such

Answer 1

Explanation:

A charge (-q) and another charge (+Q) are kept at two points A and B respectively. Keeping the charge (+Q) fixed at B, the charge (-q) at A is moved to another point C such that ABC forms an equilateral triangle of side l. The net work done in moving the charge (-q) is
