A block of mass m=2.0kg is held in equilibrium on an incline of angle=60 degrees by the horizontal force F.
a) determine the value of F
b) determine the normal force exerted by the incline on the block (ignore friction).

Solution Preview

a) We only really need to think about motion along the plane of the incline for this part of the question. There is one force pulling it down the hill. What is this force? It is the component of gravity in that direction. The gravity force acts downward. This force can be split into two orthongonal components, one acting in the direction ...
