Correctly identify the apparent weight of a lift which is moving upwards, with acceleration?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → The apparent weight of the lift shall be more than its actual weight
When a lift is moving upwards with acceleration, the apparent weight of a person in it is affected by the acceleration.
Step 1: Apparent weight formula
$W_{\text{apparent}} = W_{\text{actual}} + ma$
Where:
- $W_{\text{actual}} = mg$ (true weight)
- a = acceleration of the lift (upwards)
Step 2: Analyze
- If the lift accelerates upward, the normal force (apparent weight) increases.
- So, apparent weight > actual weight
Answer: The apparent weight of the lift shall be more than its actual weight
