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
(c) 60 N
(d) 20 N.

Answer 1

Hello Dear.

Answer :- Option (c) 60 N.

Explanation ⇒
Newton's third law of motion will be applied in the Question.
According to the Newton's Third law of motion, ''To every Action there is always an equal and opposite reaction''.

A 60 kg of the Man pushes the 40 kg man by the force of 60 N. Thus, the Reaction Force is -60 N, because resultant force is always equals in magnitude but not in acceleration. Similarly,equal and opposite reaction will be exerted by the 40 kg man on the other man.

Thus, 40 kg man will push the other man with the Force of 60 N.


Hence, Option (c) is correct.


Hope it helps. :-)

Answer 2

HEY!!

_______________________________

(c) 60 N

▶▶According to Newton's third law, which states that an action-reaction pair of forces are equal in magnitude, the man who weighs 40 kg will push the other man with the same force of 60 N.
