A person is standing in an elevator. In which situation, he experiences weight loss?
- A When the elevator moves upward with constant acceleration
- B When the elevator moves downward with constant acceleration
- C When the elevator moves upward with uniform velocity
- D When the elevator moves downward with uniform velocity
Answer & Solution
Correct Answer
(B) When the elevator moves downward with constant acceleration
Step-by-step Solution
Detailed explanation
\(mg - N = ma\) \(\Rightarrow N = m ( g - a )\) \(\therefore\) Person experiences weightloss, when acceleration of lift is downward.
