Question:

The figure shows a horizontal force acting on a block of mass M on an inclined plane (angle θ). What is the normal reaction N on the block?

mgsinθ - Fcosθ

mgcosθ - Fsinθ

mgcosθ + Fsinθ

mgsinθ + Fcosθ

Solution:

From the figure, the normal reaction on the block is N = mgcosθ + Fsinθ.
