Two identical charged spheres suspended from a common point by two light strings of length

l

, are initially ata distance

d(\ll l)

apart due to 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

. If

x

denotes the distance between the spheres, then

v

varies as

Options

A $x^{-1}$
B $x^{1 / 2}$
C $x^{-1 / 2}$
D $x$

Correct answer

C. $x^{-1 / 2}$
