Question

According to the third law of motion, action and reaction

• A. always act on the same body
• B. always act on different bodies in opposite directions
• C. have same magnitude and directions
• D. act on either body at normal to each other

Answer 1

The correct option is B

always act on different bodies in opposite directions

The explanation for the correct option:

in case of option B:

1. Newton’s third law of motion states when we exert a force on a body, we also experience a force that is equal in magnitude in the opposite direction of the force which is exerted by us.
2. Thus, the action and reaction force work on two different bodies in opposite direction and has the same magnitude.

Hence, option B is correct.
