If rope of lift breaks suddenly, the tension exerted by the surface of the lift

If rope of lift breaks suddenly, the tension exerted by the surface of the lift (a = Acceleration of lift) is

Options

(a) mg
(b) m(g+a)
(c) zero
(d) m(g-a)

Correct Answer:

zero

Explanation:

If the rope suddenly breaks, acceleration = g
So substituting in formula, tension T=m(g−a)=0
