Option (B) shows the correct diagram for direction of forces acting on the object.
Explanation:
- From question statement, a pull force is exerted on object that is kept on a rough surface.
- Due to rough surface, there will be a frictional force that acts on object to oppose this pull force.
- Also, there is a force due to gravity acting on the body due to which the object exerts its weight on the surface below.
- So, the external exerted force (P) of pull acts on the body in the direction opposite to the frictional force (F). Both of these forces are along the horizontal line.
- And the weight (W) of the body is exerted on the surface below in the downward direction.
