A charge {(-{q})} and another charge {({Q})} are kept at two p

Question

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 $A B C$ forms an equilateral triangle of side $l .$ The net work done in moving teh charge $(- q)$ is

\frac{1}{4 π ϵ _{0}} \frac{Q q}{l}

\frac{1}{4 π ϵ _{0}} \frac{Q q}{l ^{2}}

\frac{1}{4 π ϵ _{0}} Q q l
