A man weighs 80 kg. He stands on a weighing scale in a lift which is moving upwards with a uniform acceleration of 5 m//s^(2) . What would be the reading on the scale? ( g= 10 m//s^2 )

A person of mass 50kg stands on a weighting scale on a lift If the lift is ascending upwards with a uniform acceleration of 9ms^(-2) what would be the reading of the weighing scale?(g=10ms^(-1)) in kg wt

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 ?

A body of 100 kg stands on a spring weighing machine inside a lift. The lift starts to ascend with acceleration of 2.2ms^(-2) . What is the reading of the machine inside a lift. The lift starts to ascend with acceleration of 2.2ms^(-2) . What is the reading of the machine?

A block of mass m kg is kept on a weighing machine in an elevator. If the elevator is retarding upward by a ms^(-2) , the reading of weighing machine is (in kgf)
