Question

A girl weighing 25kg stands on the floor. She exerts a downward force of 250N on the floor. what force does the floor exert on her.​

Answer 1

Answer:

Her weight

Explanation:

If we assume acceleration due to gravity as 10m/s^2 then the girl's weight would be 250N. Weight is one kind of force, hence it would be her weight. And from Newton's third we know that every force has it's equal and opposite reaction. So, the floor applies the same force upwards as she applies downwards ( her weight ).
