Question

A boy of mass 50 kg standing on ground exerts a force of 500 N on the ground. The force exerted by the ground on the boy will be (a) 50 N
(b) 25000 N
(c) 10 N
(d) 500 N

Answer 1

Answer:

500 N

Explanation:

this is because according newtons thord law of motion every action has an equal and opposite reaction. in this the is exerting a force of 500newton and the ground is also exerting a force of 500 newton on it.

Answer 2

(d) 500 N

As per Newton's third law of motion. It states that, "every action has an equal and opposite reaction."

More:-

Students have many confusion regarding the 3rd law of motion. The think that if "every action has an equal and opposite reaction", then why do not they cancel each other? This is because the reaction is the result of the action.

Also, the statement, “every action has an equal and opposite reactions” IS NOT EFFECTIVE. You can write:- “Force occures in pairs and they act of different bodies.”
