AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
Two spheres ' \(A\) ' and ' \(B\) ' of equal mass lie at rest at the opposite ends of a diameter of a smooth horizontal circular groove of radius ' \(r\) '. 'A' moves and collides with ' \(B\) ' after a time ' \(t\) '. If ' \(e\) ' is the coefficient of restitution, next collision between the spheres takes place after a time of ____
- A \(\frac{2 \mathrm{t}}{\mathrm{e}}\)
- B \(\frac{\mathrm{t}}{\mathrm{e}}\)
- C \(\frac{\pi \mathrm{t}}{\mathrm{e}}\)
