Question

When a body is lying on a rough inclined plane and does not move, the force of friction

• A. Is equal to $\mu R$
• B. Is less than $\mu R$
• C. Is greater than $\mu R$
• D. Is equal to R

Answer 1

Answer: (B)

Is less than $\mu R$

Answer 2

When the body is at rest then static friction works on it, which is less than limiting friction $( \mu R )$ .
