question mark

a carpenter of mass 50 kg is standing on a weighing machine placed in a lift of mass 20 kg.
a light string is attached to the lift. the string passes over a smooth pulley and is attached to the lift and the other end is held by the carpenter.when carpenter keeps the lift moving upward with constant velocity, find-
​1. reading of the weighing machine
​2. net force on the man.
​3. net force on the weighing machine.
​4. tension of the string
