Question

rahul sits in a chair reading a book. which force is equal to the force rahul exerts on earth?
rahul’s weight
rahul’s mass
the sum of the weights of rahul and the book
the sum of the weights of the chair, rahul, and the book

Explanation:

Newton's third law states that for every action, there is an equal and opposite reaction. The force Rahul exerts on Earth is the gravitational pull he applies to Earth. The equal and opposite force is Earth's gravitational pull on Rahul, which is defined as Rahul's weight. Mass is not a force, and the other options involve additional objects that are not part of the direct action-reaction pair between Rahul and Earth.

Answer:

Rahul's weight
