A small ball of mass `m_(2)` rests on the top of a bigger ball of mass `m_(1)(gtgtm_(2)`. The centre of bigger ball is at height `3r` above ground as shown. The balls are dropped from this situation. If the smaller ball bounces to a height 4 nr from ground after its first collision with bigger ball. find n. (Assume all collisions are elastic).
