Question

What is weight of a woman standing inside a lift which is moving down with an acceleration

Answer 1

Let acceleration of the lift moving down = a .

Weight of the person with mass m
= normal reaction force exerted by the floor on the person.
= m g - m a.

Answer 2

If lift is moving downwards with acceleration “a” and mass of women is “m” then

Weight = mg
Direction: Downwards

Pseudo force = ma
Direction: Upwards

Net force = Weight - Pseudo Force
= mg - ma
= m(g - a)

Apparent weight of women = m(g - a)
