A body of mass 50kg is put on a spring weighing machine in a lift What is the reading of the machine when (i) Lift ascends with a unifrom velocity of 10m//s (ii)descends with an acceleration of 5m//s^(2) ? Take of = 10m//s^(2) .

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 descending with a constant velocity of 2 m/s.

A woman weighing 50 kgf stands on a weighing machine placed in lift. What will be the reading of the machine, when the lift is (i) moving upwards with a uniform velocity of 5ms^(-1) and (ii) moving downwards with a uniform acceleration of 1ms^(-2) ? Take g = 10 ms^(-2) .
