Question

A body is exerting a force of 10 N on a table. The table will exert a force of on the body.

• A. $8\text{N}$
• B. $10\text{N}$
• C. $12\text{N}$

Answer 1

The correct option is B $10\text{N}$

Newton's third law of motion states that every action has an equal and opposite reaction. So, if a body is exerting a force of $10\text{N}$, it will experience a reaction force of $10\text{N}$. The reaction force will always be equal in magnitude, but opposite in direction, to the action force.
