The apparent weight of a man in a lift is less than the real weight when the lift is going

A man of mass m is on the floor of a lift. The lift moving up with acceleration 'a', then (a) the net unbalanced force on him is 'ma' (b) the normal reaction exerted by the floor on the man is m(g + a) (c ) the apparent weight is greater than his true weight

A man of mass m is on the floor of a lift. The lift moving up with acceleration 'a', then : a) the net unbalanced force on him is 'ma' b) the normal reaction exerted by the floor on the man is m(g + a) c) the apparent weight is greater than his true weight

Statement A : If the lift is falling freely then the man on its floor experiences no reaction from the floor. Statement B : If the lift moves down with an acceleration a gt g , then the normal reaction becomes negative and the man feels floating up in the lift.
