Question

4. Name each of the forces labelled P, Q and R​

Answer 1

Hey MATE!!!

The diagram can't be understood properly but I can give you the most appropriate answer possible, therefore my inbox is open for your doubts.

Since, P is acting between two surface therefore it must be normal contact force.

Q is acting in downward direction therefore it is surely gravitational force on the block.

R is acting as if it is opposing the motion of block therefore, it must be friction force.

Hope it helps
