Question

Normal reaction of plane R =.......​

Answer 1

Explanation:

If a particle of mass m is placed on a rough inclined plane (i.e. the frictional force F≠0), the particle may be prevented from sliding if F is large enough. We resolve perpendicular to the plane (as the normal reaction R acts at a right angle to the plane), where acceleration is zero.

Answer 2

Answer:

I, the normal force is the component of a contact force that is perpendicular to the surface that an object contacts.[1] For example, the surface of a floor or table that prevents an object from falling. In this instance normal is used in the geometric sense and means perpendicular, as opposed to the common language use of normal meaning common or expected. For example, a person standing still on flat ground is supported by a ground reaction force that consists of only a normal force
