A smooth sphereAof massmcollides elastically with an identical sphereB...
Sphere A moving with velocity v has a component v/2 along the line joining the centres of the spheres at the time of collision and another component perpendicular to the previous direction. After collision the component along the line will interchange i.e. B will move with v/2 velocity i.e., 4 m/s along the line joining the centres and A moves with 
velocity at perpendicular direction to B.
velocity at perpendicular direction to B.The correct answers are: the direction of motion of A and B after collision are at right angles, the speed of B after collision is 4 m/s
