Question

An object with a mass of `2 kg` is on a plane with an incline of `pi/8`. If the object is being pushed up the plane with `3 N` of force, what is the net force on the object?

Answer 1

Here,the component of weight of the object which tries to pull it down the plane is `mg sin (pi/8) = 7.65 N`

This is higher than the applied force of `3 N` up along the plane.

So,net force acting on the object is `(7.65-3)N = 4.65 N` down the plane
