A solid uniform disk of mass `m` rolls without slipping down a fixed inclined plane with an acceleration `a`. Find the frictional force on the disk due to surface of the plane.

Text Solution

Verified by Experts

The correct Answer is:
`1//2 ma`
From previous question
`f xx R = I alpha`
`f = (mK^(2))/(R^(2)) a` for disc `= (K^(2))/(R^(2)) = (1)/(2)`
`f = (ma)/(2)`.
