Friction: Practice Problem & Solution
A block of mass M is placed on a fixed smooth inclined plane of inclination 'A' with the horizontal is at rest. The force exerted by the plane on the block has a magnitude:
Solution Explained:
To solve this problem, we apply the core principles of Friction. Understanding the underlying formula is key to arriving at the correct answer below:
As the object on inclined plane is at rest net force acting on the object is zero. Force applied on object by earth is Mg. Resultant of Normal reaction and friction force will cancel gravitational force. So the force applied by inclined plane on block is Mg in vertically upward direction.
