Expert Answer
As the cable breaks suddenly the lift will act as a freely falling body.
Thus,
acceleration of lift = acceleration due to gravity
a = g ...(1)
Thus, a normal reaction by the floor on a woman (N) = Weight of woman - upward force on a woman
N = W - ma = mg - mg = 0 ...(from (1))
Thus, net force exerted by the floor of an elevator on a woman is zero.
