When the lift is moving upward with a uniform acceleration, the apparent weight of the body inside it will be:
Correct answer: B. More than its actual weight
- A. Less than its actual weight
- B. More than its actual weight
- C. Varying with velocity
- D. The same as its actual weight
Explanation
When the lift is moving upward with a uniform acceleration, the apparent weight of the body inside it will be more than its actual weight. This is because the normal force (which contributes to the apparent weight) is greater than the actual weight due to the upward acceleration.

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.
