Two identical spheres A, B are in a smooth horizontal circular smooth groove at opposite ends of a diameter. A is projected along the groove and it impinges on B in a time interval T. Let e be the coefficient of restitution, the

Two equal sphere A and b lie on a smooth horizontal circle groove at opposite ends of a diameter. At time t= 0,A is projected along the groove and tis first implings on B at time t = T_(1) and again at time t = T_(2). If e is the coefficient of restitution, the ratio T_(2)//T_(1) is

Two equal spheres A and B lie on a smooth horizontal circular groove at opposite ends of a diameter. At time t = 0 , A is projected along the groove and it first impinges on B at time t = T_(1) and again at time t = T_(2) . If e is the coefficient of restitution, the ratio T_(2)//T_(1) is

Two sphere A and B of equal masses lie on the smooth horizontal circular groove at opposite ends of diameter and at the end of time 't','A' impings on 'B' . If 'e' is the coefficient of restitution, the second impinge will occur after a time
