An object of mass `M` and radius `R` is performing pure rolling motion on a smooth horizontal surface under the action of a constant force `F` as shown in Fig. The object may be

Options

A. disk
B. ring
C. solid cylinder
D. hollow sphere

Answer

B

Explanation

`F=Ma`
`FR=Ialpha`
For pure rolling `a=Ralpha`

Solving the above equations we get `I=MR^(2)`
So the object may be a ring or a hollow cylinder.
