A man of mass 90 kg is standing in a lift whose cable broke suddenly. If thelift falls freely, the force exerted by the floor on the man is

A

90N

B

180N

C

Zer N

D

`-90N`

Text Solution

Verified by Experts

The correct Answer is:
C
The lift is a freely falling body with an acceleration g.
`therefore` Apparent weight =m (g-a)=0
the force exerted by the floor on the man is zero.
