Two identical charged spheres suspended from a common point by two massless strings of length `l` are initially a distance d ( d ltlt l) apart because of their mutual repulsion . The charge begins to leak from both the spheres at a constant rate As a result the charge approach each other with a velocity `v`. Then as a function of distance `x` between them .
A. `vprop x^(1//2)`
B. `v propx`
C. `v prop x^(1//2`
D. `c propx^(-1)`
