Question

when a man slides down a smooth inclined it moves back on smooth surface because of this force (N- Normal reaction, mg is weight of the body )

Answer 1

Explanation:

if we break the components of normal along the incline and perpendicular to the incline ..

then.. normal is equal to the perpendicular component of mg that is mgcosx

Answer 2

Answer:

When a man slides down a smooth inclined surface, he moves back on a smooth surface due to at least two forces: gravity and normal force. While the normal force acts perpendicular to the surface, the force of gravity, often known as weight, acts downward.

Explanation:

• On a surface that is inclined, an object will frequently slip downward.
• The amount of tilt in the surface affects how quickly the object slides down; the more tilt there is on the surface, the faster the object will slide down it.
• A tilted surface is referred to as an inclined plane in physics.
• A known imbalanced force causes objects to accelerate down inclined planes.
• It is crucial to examine the forces acting against an object on an inclined plane in order to comprehend this form of motion.
• Any object that is placed on an inclined plane will always be subject to at least two forces: gravity and normal force. Although the normal force acts perpendicular to the surface, the force of gravity, often known as weight, acts downward.

Thus, When a man slides down a smooth inclined surface, he moves back on a smooth surface due to at least two forces: gravity and normal force. While the normal force acts perpendicular to the surface, the force of gravity, often known as weight, acts downward.
