The solid cylinder and a hollow cylinder, both of the same mass and same external diameter are released from the same height at the same time on a inclined plane. Both roll down without slipping. Which one will reach the bottom first?NEET 2010 (Mains)

Options:

Answer:

Solution:

$t = \frac{1}{s i n θ} \frac{2 h}{g} (1 + \frac{k ^{2}}{R ^{2}})$ If a solid and hollow body of same shape are allowed to roll down on inclined plane then as $(\frac{k ^{2}}{R ^{2}})_{S} < (\frac{k ^{2}}{R ^{2}})_{H}$ , solid body will reach the bottom first with greater velocity.
