A body of mass \( 50 \mathrm{~kg} \), is suspended using a spring balance inside a lift at rest. If the lift starts
falling freely, the reading of the spring balance is
- A \( 50 \mathrm{~kg} \)
- B > \( 50 \mathrm{~kg} \)
- C \( 60 \mathrm{~kg} \)
- D \(=0 \)
Answer & Solution
Correct Answer
(D) \(=0 \)
Step-by-step Solution
Detailed explanation
Given, a body of mass \( 50 \mathrm{~kg} \) is suspended using spring inside a lift.
If lift falls freely, then there is a condition of weightlessness, thus the reading of the spring balance is \( 0 \).
If lift falls freely, then there is a condition of weightlessness, thus the reading of the spring balance is \( 0 \).
