A person of mass m is standing in a lift. Find his apparent weight when the lift is (i) moving upwards with uniform acceleration a,

A person of mass m is standing in a lift. Find his apparent weight when the lift is (iii) Falling freely (g is the acceleration due to gravity).

Find out the expressions of apparent weight of a man in a lift when the lift is coming down with an acceleration (i) a = g and (iii) a gt g.

A spring balance is set in a stationary lift. A person of mass 50 kg is standing on the balance. What will be the change in the balance reading when the lift moves upwards with constant acceleration?

A spring balance is set in a stationary lift. A person of mass 50 kg is standing on that balance. What will be the change in the reading of the balance if the lift moves upwards with constant velocity?

A spring balance is attached to the roof of a lift. A man hanged his bag from the spring balance. The reading of the spring balance is 49N when the lift is not moving. When the lift will move downward with the acceleration 5m//s^2 , then the reading of the spring balance will be:

A lift of mass 400 kg is hung by a wire. Calculate the tension in the wire when the lift is (a) at rest, (b) moving upward with a constant acceleration of 2.0 m//s^(2) and (c) moving downward with an acceleration 2.0 m//s^(2) .

A lift of mass 200 kg is moving up with an acceleration of 4 m cdot s^(-2) . What is the tension in the lift cable? If the lift moves down with the same acceleration, what will be the tension in that case? [ g = 9.8 m cdot s^(-2) ]
