Two identical charged shperes suspended from a common point by two massless strings of lengths 
are initially at a distance 
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
