Question

An object with a mass of `2 kg` is on a plane with an incline of `pi/12`. If the object is being pushed up the plane with `19 N` of force, what is the net force on the object?

Answer 1

From the diagram, we can see that the magnitude of applied force upwards,along the plane is higher than the `sin theta` component of its weight,which acts against the motion due to the applied force,

So,net force acting is `(19-5.176) N` or, `13.824 N` upwards along the plane.
