Question

Which of the following best describes normal force? A. the force of attraction between two objects B. the force applied to an object by a push or a pull C. the force transmitted through a string, rope, or wire D. the support force exerted on an object which is in contact with another stable object

Answer 1

B. the force of applied to an object by a push or pull

Answer 2

Answer:

D. the support force exerted on an object which is in contact with another stable object

Explanation:

When two bodies are in contact with each other then their contact surface will exert force on each other.

This is an electromagnetic force due to which two bodies will push each other in opposite directions.

This force always follows Newton's III law and hence it always exist in form of action and reaction pair.

So the correct answer for normal force is given as

D. the support force exerted on an object which is in contact with another stable object
