An object of mass M = 924 g is pushed at a constant speed up a frictionless inclined surface which forms an angle è = 50 degrees with the horizontal as shown in the figure below. What is the magnitude of the force that is exerted by the inclined surface on the object?

There is an F shown, at an angle in the figure.

That angle is important.
Answered by drwls
The direction of the applied force is important, and so it the angle of the incline. Apply vertical and horizontal forces balance equations to solve.
