A block which has a weight of 130 Newtons is at rest on the incline plane shown
above. There is no friction between the block and the incline. The incline
has sides of length n1 and n2 meters. A
cord is attached to the block to keep it from sliding down the incline. What is
the magnitude of the force that the incline exerts on the block? If the magnitude
of the incline's force is n3 Newtons, what is n3?
