When a body moves up a rough inclined plane then it is acted upon three forces. (option c)

• The three forces are :

- Gravitational force.

- Frictional force.

• The pull force is acting upon the body because the body is moving on the inclined plane.

• The gravitational force is acting upon the body because the body has certain amount of mass.

• The frictional force is acting upon the body because the surface of the inclined plane is rough.
