Two identical balls A and B of equal mass are lying on a smooth surface as shown in the figure. If ball 'A' hits ball 'B' at rest with a velocity 16 ~ms ⁻¹ , then the co-efficient of restitution between A and B so that B just reaches the highest point of the smooth inclined plane is ( g =10 ~ms ⁻² )
