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. ` v alpha x^(-1)`
B. `v alpha x^(1//2)`
C. `v alpha x `
D. `v alpha x^(-1//2)`

Answer

A
