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.

Students are less likely to get help when the name changes with questions of the same type, posted so close together. Please do not use name changes to get more of your questions answered. It doesn't work with me

Just plug in the numbers likewise:

N= mg/ cos (theda)

That will give you your answer!
