A person of 60 kg descends in a lift with an acceleration `2 m^(-2)` The cable of lift suddenly breaks down. The weight of the person inside the lift is

A

60 g

B

zero

C

62 g

D

58 g

Text Solution

Verified by Experts

The correct Answer is:
B
When the lift moves down with uniform acceleration a, the apparent weight of the person is `W_1 = m(g -a)`
When cable break, lift falls with acceleration = g
`W_2 = m(g - g)` = zero
