A \( 10 \mathrm{~kg} \) stone is suspended with a rope of breaking strength \( 30 \mathrm{~kg} \) wt. The minimum time in which the stone can be raised through a height \( 10 \mathrm{~m} \) starting from rest is (taking \( g=10 \mathrm{~N} / \mathrm{kg} \) )
[AMU PMT 2009]
(a) \( 0.5 \) seconds
(b) \( 1.0 \) seconds
(c) \( \sqrt{\frac{2}{3}} \) seconds
(d) \( 2.0 \) seconds
