Two identical charged spheres suspended from a common point by two massless strings of lengths l, are initially at a distance d (d much less than 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 them, is
