Question

The force that a solid surface exerts on any object in the normal
direction is called
a) Muscular force
b) Normal Force
c) Tension force
d) Magnetic force​

Answer 1

Answer:

option b is right answer.

Answer 2

Answer:

b) Normal Force

Explanation:

A Normal Force (also called as Normal Reaction Force) is a contact-force that acts on any object exerted by a solid surface.

For example, take a book lying on the table. The book exerts some force (F1) to the table due to its weight. The table also exerts an equal and opposite force (F2) to the book to make it stable. Thus, we can say F1=F2.

Basically, Normal Reaction Force is the result of the Frictional force between two objects.
