Question

For every action force, there is: A. a net force. B. an unbalanced force. C. a friction force. D. an equal and opposite force. E. all of these

Answer 1

The correct option is 'D': Equal and opposite force.

Step-by-step explanation:

We know from Newton's third law of motion

"For every action there exists an equal and opposite reaction".

The statement is further explained as

If there exists a force from Body 1 to Body 2 then Body 2 must also exert an equal and opposite force on the Body 1.

In simple terms we can say that the action and the reaction forces exist in pairs and are always present if any one among them is present.
