Answer 1

Answer on Question #56533-Physics-Mechanics-Relativity

A block of mass $m$ is released on a smooth inclined plane of inclination theta with the horizontal the force exerted by the plane on the block has a magnitude

Solution

where $N$ is Normal force that is perpendicular to the plane, $W = mg$ , where $m$ is mass, $g$ is acceleration due to the gravity, and $\theta$ is Angle of inclination of the plane, $f$ is friction force.

Plane is smooth, so $f = 0$ .

The force exerted by the plane on the block is Normal force:

$N = mg\cos \theta$

Answer: $mg\cos \theta$
