Solution

The correct option is C

0 N


As we know that, during free fall the only force acting is a man's weight itself. So, both lift and the boy inside would be in a state of free fall and hence the normal contact force between the weighing machine and the man would be zero. Therefore the reading of the scale would be zero.
