Two identical charged spheres suspended from a common point by two massless strings of length `l` are initially a distance `d (d lt lt l)` apart because of their mutual repulsion. The charge begins to leak from both the spheres at a constant rate. As a result the charges approach each other with a velocity `v`. then, as a function of distance x between them

Options

A. `vprop"x"`
B. `vprop"x"^(-(1)/(2))`
C. `vprop"x"^(-1)`
D. `vprop"x"^((1)/(2))`
