Question

Forces of action and reaction act:

• A. one after the other on same body
• B. simultaneously on same body
• C. one after the other on different bodies
• D. simultaneously on different bodies

Answer 1

The correct option is D

simultaneously on different bodies

Explanation of correct option

(D):simultaneously on different bodies

1. Newton's third rule of motion says that "To every action, there is always an equal and opposite reaction"
2. For example, the weight of the book produces a downward force on the table, while the table exerts an upward force on the book.
3. As a result, action and reaction impact two separate bodies simultaneously.

Explanation of incorrect option(s)

(A): one after the other on the same body: Both action and reaction happen simultaneously, but on different bodies, because action and reaction do not have the same effect on the same body.

(B): simultaneously on the same body: The action and reaction will not have the same effect on the same body.

(C): one after the other on different bodies: In nature, both action and reaction occur simultaneously, which indicates that there will be a reaction until the action occurs.

Hence, forces of action and reaction act simultaneously on different bodies. Hence option (d) is correct.
