Passage / Comprehension

A cylinder and a ring of same mass M and radius R are placed on the top of a sufficient rough inclined plane of inclination $θ$ . Both are released simultaneously from the same height h.

Identify the correct statement(s).

Options:(select one or more)

Answer:

B, C

Solution:

$m g h = \frac{1}{2} m v^{2} + \frac{1}{2} I \frac{v ^{2}}{R ^{2}}$

Ring ( $I = m R^{2}$ ): $v = g h$ ; cylinder ( $I = \frac{1}{2} m R^{2}$ ): $v = \frac{4 g h}{3}$

$f = \frac{m g s i n θ \cdot I / m R ^{2}}{1 + I / m R ^{2}}$ , so friction is larger for the ring
