Question

While standing in a low tunnel, you raise your arms and push against the ceiling with a force of 100 n. your mass is 70 kg. what force does the ceiling exert on you?

Answer 1

The ceiling exerts an equal and opposite force of 100 N on the person, following Newton's Third Law of Motion.

Step-by-step explanation:

When standing in a low tunnel and pushing against the ceiling with a force of 100 N, by Newton's Third Law of Motion, the ceiling exerts an equal and opposite force of 100 N on you. This is because for every action, there is an equal and opposite reaction. Hence, if you push against an object with a certain force and there is no acceleration or movement, that object must be pushing back with the same force.

Answer 2

This is a manifestation of Newton's third law of motion called the Law of Action-Interaction. It states that when a body is at rest or not moving, for every force exerted on the object, an equal,opposite force is exerted also towards you. Thus, the ceiling also exerts an equal force of 100 Newtons.
