Explanation:
The reading of
If the elevator is at rest then the reading of the scale would be exactly the weight
But here we have a situation of acceleration or non-equilibrium between the two forces and so the normal reaction has to be different.
If we cut the cable of the elevator the reaction would disappear and the acceleration (downwards) would be exactly
