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
A
B
C
D
Zero
Text Solution
Verified by ExpertsThe correct answer is:
D
According to figure, potential at A and C are equal. Hence work done in moving – q charge from A to C is zero.
