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 AIs moved to another point C such that ABC forms an equilateral triangle of side l.find net workdone in moving charge q.

when charge is at A then potential is (-Qq/4piE0l)
at B it is also same as distance remains equal due to formation of equilateral triangle of side l
so,potential difference is 0 and hence work done is 0.
