Two identical charged spheres suspended ...

Two identical charged spheres suspended from a common point by two massless strings of lengths /, are initially at a distance `d(dltltI)` 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

`VooX^(-1/2)`

B

`VooX^-1`

C

`VooX^(1/2)`

D

`VooX`
