The minimum acceleration with which a fireman can slide down a rope of breaking strength two - third of his weight is

Text Solution

Verified by Experts

The correct Answer is:
0.33
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 `implies`
`m (g - a) = (2)/(3) mg implies a = g - (2g)/(3) = (g)/(3) = 0.33 g`
