Two identical charged spheres suspended from a common point by two mass-less strings of length l are initially at a distance d ( dl) 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 .

are placed at certain distance apart and force acting between them is F. If 25% charge of A is transferred to B having charges +Q and -Q respectively then force between the charges becomes Two point charges A and B
