Question

A 60 kg man pushes a 40 kg man by a force of 60 N. The 40 kg man has pushed the other man with a force of
(a) 40 N
(b) 0 N
(c) 60 N
(d) 20 N

Answer 1

Option (c) is correct.

Explanation:

• Newton's third law of motion are going to be applied within the Question.

• According to the Newton's Third law of motion, ''To each Action there's forever associate equal and opposite reaction''.

• A 60 kilogram of the person pushes the 40 kilogram man by the force of 60 Newton .
• Thus, the Reaction Force is -60 N, as a result of resultant force is usually equals in magnitude however not in acceleration.
• Similarly, equal and opposite reaction are going to be exerted by the 40 kilo gram man on the opposite man.

• Thus, 40 kilo gram  man can push the opposite man with the Force of 60 N.

• Hence, option (c) is correct.
