Question

2. Trisha whose weight is 500N is standing on the ground. How much force does
the ground exert on her?
a. Less than 500N
b. Equal to 500N
c. More than 500N.
d All of these​

Answer 1

• Newton's third law of motion states that every action has an equal and opposite reaction.

For example, if someone throws a ball on a wall with 5N force, the wall will apply an equal and opposite force of 5 N on the ball.

• In this case, Trisha is standing on the ground and 50 N force is applied on the ground due to her weight.

      Therefore, the ground will apply an equal and opposite reaction force of

      500 N on Trisha.

    The correct answer will be option b.

Answer 2

Option b is correct

b. Equal to 500N

Every action has an equal and opposite response, according to Newton's third rule of motion.

If someone tosses a ball with a force of 5 N against a wall, the wall will apply an equal and opposing force of 5 N to the ball.

Trisha is standing on the ground in this scenario, and her weight exerts a 50 N strain on the ground.

As a result, the earth will exert a reaction force of equal and opposite magnitude.

Trisha receives 500 N.

Option b is the right response.
