When the lift falls with an acceleration equal to "g", the apparent weight of an object inside it will:
Correct answer: C. Become zero
- A. Remain the same
- B. Become half
- C. Become zero
- D. Become double
Explanation
In free fall, the lift and everything inside it are accelerating downward at the same rate as gravity. In this scenario, there is no contact force (normal force) acting on the object; it is essentially in a state of weightlessness. As a result, the object experiences zero apparent weight, and it will feel as if it is in a state of weightlessness, just like astronauts in free fall during space travel.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
