When a body is lying on a rough inclined plane and does not move, the force of friction
When a body is lying on a rough inclined plane and does not move, the force of friction
is equal to $\mu R$
is less than $\mu R$
is greater than $\mu R$
is equal to $R$
When a body is lying on a rough inclined plane and does not move, the force of friction
When the body is at rest then static friction works on it, which is less than limiting friction $(\mu \;R)$.
