An object of mass 5 kg is attached to the hook of a spring balance and the balance is suspended vertically from the roof of a lift . The reading on the spring balance when the lift is going up with an acceleration of `0.25ms^(-2)` is (g=10`ms^(-2))`

A

A)51.25N

B

B)48 . 75 N

C

C)52.75 N

D

D)47.25 N

Text Solution

Verified by Experts

The correct Answer is:
A
On moving upward ,
weight , `w=m(g+a)=5(10+0.25)`
`=5xx10.25`
`=51.25N`
