Question

A charge 5micro coulomb is placed at a point what is the work
required to carry 1 micro coulomb of charge once around it in a
circle of l2cm radius.​

Answer 1

Answer:

For a square ABCD, OA=OB=OC=OD=r

As charge 5μC is placed on center O so every point A,B,C and D have same potential V=5k/r.

Thus potential difference (dV) between A and B will be zero.

Work done W=qdV=1(0)=0
