A) \[\frac{2}{3}g\]
B) g
C) \[\frac{1}{3}g\]
D) Zero
Correct Answer: C
Solution :
If man slides down with some acceleration then its apparent weight decreases. For critical condition rope can bear only 2/3 of his weight. If a is the minimum acceleration then, Tension in the rope \[=m(g-a)\]= Breaking strength Þ \[m(g-a)=\frac{2}{3}mg\] Þ\[a=g-\frac{2g}{3}=\frac{g}{3}\]
