A man of mass 60 kg records his wt. on a weighing machine placed inside a lift. The ratio of wts. Of man recorded when lift is ascending up with a uniform speed of 2 m/s to when it is descending down with a uniform speed of 4 m/s will be

A

2

B

1

C

0.5

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
There is no change in weight of the man, because the lift is moving up or down with uniform speed.
`therefore ` Ratio of weights = 1
