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 `1 N` of force, what is the net force on the object?

Answer 1

here,the component of the weight acting downward along the plan is `mg sin (pi/12) = 5.17 N`

now,given, `1N` force has been applied upwards along the plane.

So,net force acting on the object is `(5.17-1N)= 4.17 N` downwards along the plane.
