Two identical spheres A and B of radius r are released simultaneously from the positions as shown, in a vessel C of radius (R + r) and which moves on a smooth surface. If coefficient of restitution is \(\frac{1}{2}\), find the velocity of A after collision with B.
- \(\sqrt{2 \mathrm{gR}}\)
- \(\sqrt{\mathrm{gR}}\)
- \(\sqrt{\frac{\mathrm{gR}}{2}}\)
- \(2 \sqrt{\mathrm{gR}}\)
Answer
(C) gR 2
