Two identical charged spheres suspended from a common distance
d
(
d
<
<
1
)
apart because of their mutual repulsion. The charged 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
