Tension in rope TC (breaking load =(2/3) mg) m(g-a)<(2/3)mg

Q. A man wants to slide down a rope. The breaking load for the rope is $\frac{2}{3}$ rd of the weight of the man. With what minimum acceleration should fireman slide down?

$g /4$

$g /3$

$2 g /3$

$g /6$

Tension in rope TC (breaking load $= \frac{2}{3}$ mg) $m (g - a) < \frac{2}{3} m g$
