Question

A block of mass m is placed on a smooth inclined plane of inclination θ with the horizontal. The force exerted by the plane on the block has a magnitude
(a) mg
(b) mg/cosθ
(c) mg cosθ
(d) mg tanθ

Open in App

Solution

(c) mg cosθ

From the free-body diagram,
N = mg cosθ
Normal force exerted by the plane on the block is mg cosθ.
