Answer:

Two point like charges q1=4.0 nCq1=4.0 nC and q2=1.0 nCq2=1.0 nC occupy fixed positions in free space. If at every point on a curve surrounding the charges as shown in the figure, net electrostatic potential V created by these charges is 900 V, what should the separation between the charges be (
