A solid sphere of mass $\displaystyle M$ and radius $\displaystyle R$ lies on a horizontal rough surface. A horizontal force $\displaystyle F$ is applied at the centre of the sphere. The acceleration of the centre of the sphere will be :
(the sphere rolls without slipping)
Official answer
(4)
$\displaystyle \frac{5 F}{7 M}$
