When a lift is moving upward with a uniform velocity, the apparent weight of a body inside the lift will be:
Correct answer: A. Equal to its actual weight
- A. Equal to its actual weight
- B. Less than the actual weight
- C. More than the actual weight
- D. Zero
Explanation
When a lift is moving upward with a uniform velocity, the apparent weight of a body inside the lift is equal to its actual weight. This is because the forces acting on the body, including gravity and the lift's acceleration, are balanced, resulting in no net force affecting the body's weight.

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.
