Question:

Correctly identify the apparent weight of a lift which is moving upwards, with acceleration?

Options:

The apparent weight of the lift shall be more than its actual weight

The apparent weight of the lift shall be less than its actual weight

The apparent weight of the lift shall be equal to actual weight

The apparent weight of the lift shall be Zero

Correct Answer:

The apparent weight of the lift shall be more than its actual weight

Explanation:

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
