You are pulling a heavy crate (mass m) up a ramp inclined at an angle θ to the horizontal. The ramp is not a smooth surface. The rope that you are pulling with is parallel to the incline.

What forces are acting on the crate?

Friction, gravity, normal force and tension

Gravity and tension

Friction, gravity and tension

Friction

Gravity, normal force and tension

Gravity

Normal force

Tension

ANSWER:- Friction, gravity , Normal force and tension.

Explanation:- as the crate is in the rough inclined plane so it has some mass then gravity also work on it where as the perpendicular component of gravity is Normal force which will also work on the crate. now surface is rough so that means friction is also present there. you are pulling the crate with the help of rope so the tension on the rope will be another force to help the crate to move on inclined.
