Question

A man is standing on a weighing machine in a lift which is moving. The weighing machine will slow MINIMUM reading when, the lift is moving?​

Answer 1

Answer:

when body free fall under gravity the weight of man is minimum

Explanation:

here we can use the concept of geff

• when body moving upwards with uniform acceleration then net weight=m×geff=m×(g+a)
• when body moving downwards with uniform acceleration then net weight=m×geff=m×(g-a)
• when body free fall due to failure of the lift mechanism then geff=0. net weight=m×0=0
