Answer #1

The apparent weight of an object in a lift accelerating downwards is

N=m(g-a) where g is the acceleration due to the gravity and a is the acceleration of the lift. It is clear from the equation that the normal reaction is less than the actual weight when the lift is accelerating downwards.

d) the normal force is less than your weight.
