PhysicsEasysingle choice

A solid sphere of mass $M$ and radius $R$ is pulled by a force $F$ as shown in figure. If the sphere does not slip over the surface, then frictional force acting on the sphere is

Options:

Answer:

Solution:

$F \times 2 R = \frac{7}{5} M R^{2} \times (\frac{a_{e}}{R})$

$\Rightarrow a_{e} = \frac{10 F}{7 M}$

$∴ F + f_{s} = m \times a_{e}$

$\Rightarrow f_{s} = \frac{3 F}{7}$
