# Two identical small metallic sphere each of mass m, each carry charge q are suspended from a common point by silk thread each of length l in equilibrium separation between the balls is x and x<<l. now each sphere starts licking its charge at the rate dq/dt such that the two balls approach towards each other the relative velocity of approach is given by v=a/√ x , where a is constant.find the value of dq/dt.
