A body of mass 50 kg is hung by a spring balance in a lift. Calculate the reading of the balance when :
The lift is ascending with an acceleration of `2m//s^(2)`.

Text Solution

Verified by Experts

Mass of body = 50 kg
Lift is descending with an acceleration of 2 `m//s^(2)`.
`" "W=m(g-a)`
`" "W=50(9.8-2)`
`" "W=50 times 7.8`
`" "=390N or 39.79 kg`.
