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 0.25 `ms^(-2)` is take, (take, `g=10ms^(-2)`)

A

51.25 N

B

48.75 N

C

52.75 N

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`
