A large block of ice 4 m thick has a vertical hole drilled through it and is floating in the middle of water in a lake. The minimum length of rope required to scoop up a bucket full of the through the hole is (density of ice `=0.9CGS` unit, density of water `=1CGS` unit)

A

40 cm

B

24 cm

C

20 cm

D

360 cm

Text Solution

Verified by Experts

The correct Answer is:
A
`Mg =V_("in")d_(l)g, Ald_("ice")=Al_("in")d_(l)`
Length of rope = side of the block `-l_("immersed")`
