Question : Two identical charged spheres suspended from a common point by two massless strings of length l, are initially at a distance d (d<<l) apart because of their mutual repulsion. The charges begin to leak from both the spheres at a constant rate. As a result , the spheres approach each other with a velocity v. Then v varies as a function of the distance x between the spheres, as
a) v∝x-1/2
b) v∝x-1.
c) v∝x1/2
d) v∝x
