A force t=312n up and incline is reward to keep a body at rest on a fritionless inclined plane which make an angle of 35degress with horizontal. Draw a force diagram and label all the force acting on a body. Calculate the magnitude of the force due to gravity and the normal force

energy
Fp = Mg*sin35 = 315
Mg = 315/sin35 = 549 N. = Force of gravity.

Fn = Mg*Cos35 = 549*Cos35 = 450 N. = Normal force.
