Two identical spheres A and B lie on a smooth horizontal circular groove at opposite sides of diameter. A is projected along the groove and at the end of time 't', impinges on B. If 'e' is the coefficient of resitution, the second impact will occur after a time...???A. 2t/eB. t/eC. (pie)t/eD. 2(pie)t/eplease elaborate the answer...rates assured...

The answer is A. After 1st impact the velocity will be V.e.and to cover the distance it travelled i.e half of the circle it needs time T.e.even if the B is not at rest the relative velocity will equal to initial velocity of A.so it does not effect the time required .
