Homework Statement
A tangential force F acts at the top of a thin spherical shell of mass m and radius R. Find the acceleration of the shell if it rolls without slipping.
Homework Equations
Since the shell is rolling, friction does not act at the bottom.
So equating the torque,
F*R= I*α
The Attempt at a Solution
So putting in value of Moment of inertia for a hollow sphere, I=2/3mR^2
and α=a(COM)/R
And solving for a, i got a=3F/2m
But the correct answer is : 6F/5m
Where am i going wrong?
