Two identical charged spheres suspended form a common point by two massless strings of lengths l, are initially at a distance d(d gt gt l) apart because of their mutual repulsion. The charges brgin 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

Two identical charged spheres of material density rho , suspended from the same point by inextensible strings of equal length make an angle theta between the string. When suspended in a liquid of density sigma the angle theta remains the same. The dielectric constant K of the liquid is

Two positively charged sphere of masses m_(1) and m_(2) are suspended from a common point at the ceiling by identical insulating massless strings of length l . Charges on the two spheres are q_(1) and q_(2) respectively. Equilibrium both strings make the same angle theta with the vertical. then

Three identically charged, small spheres each of mass m are suspended from a common point by insulated light strings each of length I. The spheres are always on vertices of an equilateral triangle of length of the sides x (ltlt l) . Calculate the rate dq/ dt with which charge on each sphere increases if length of the sides of the equilateral triangle increases slowly according to law (dx)/(dt)=(a)/(sqrt(x))
