PhysicsEasysingle choice

A tangential force $F$ acts at the top of a thin spherical shell of mass $m$ and radius $R$ . The acceleration of the shell, if it rolls without slipping is

Options:

Answer:

Solution:

torque about 'O' $τ = I α$

$F (2 R) = α \frac{5}{3} m R^{2}$

$α = \frac{6 F}{5 m R}$

Linear acceleration $a = R α = \frac{6 F}{5 m}$
