When a man in moving lift feels himself weightless?

When a person inside a lift, -will feel superweightlessness? Explain with equation.

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

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 person of mass m is standing in a lift. Find his apparent weight when the lift is (ii) moving downwards with uniform acceleration a( lt g),

A person inside an artificial satellite revolving around the earth feels weightless- true or false ?

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).
