If a 60 kg man pushes a 40 kg man with a force of 60 N , the force exerted by the 40 kg man on the other man is

Options

A20 N
B60 N
C40 N
D0

Correct answer

B. 60 N

Step-by-step solution

According to Newton's third law of motion, to every action, there is an equal and opposite reaction. The force exerted by the 60 kg man on the 40 kg man is 60 N . Therefore, the 40 kg man exerts an equal and opposite force on the 60 kg man. The magnitude of the force exerted by the 40 kg man is 60 N .
