Two idential charged spheres suspended from a common point by two massless strings of lengths l, are intially at a distance d(d<<1) a part because of their mutual repulsion. The charges begin to leak from both the spheresapproach each other with a velocity v.Then v varies as a function of the distance x between the spheres as:

A

`nu alpha x^-1`

B

`nu alpha x^(1//2)`

C

`nu alpha` x

D

`nu alpha x^-(1//2)`
