A solid cylinder of mass $$m$$ is wrapped with an inextensible light string and, is placed on a rough inclined plane as shown in the figure. The frictional force acting between the cylinder and the inclined plane is:

[The coefficient of static friction, $$\mu_s$$, is 0.4]

A

$$\frac{7}{2}mg$$

B

$$5mg$$

C

$$\frac{mg}{5}$$

D

0
