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 \(16 \mathrm{~ms}^{-1}\), then the co-efficient of restitution between \(A\) and \(B\) so that \(B\) just reaches the highest point of the smooth inclined plane is \(\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)\)
- A \(\frac{2}{3}\)
- B \(\frac{1}{2}\)
