A man of mass 70 kg stands on a weighing machine in a lift , which is moving (a) upwards with a unifrom speed of `10^(-1)` (b) downwards with a unifrom acceleration of `5 ms^(-2)`
(c) upwards with a unifrom acceleration of `ms^(-2)` What would be th readings on the scale in each case ?
(d) What would be the reading if the lift machanism failed and it hurtled down freely under gravity ?
