A small wooden ball of density `rho` is immersed in water of density `sigma` to depth h and then released. The height H above the surface of water up to which the ball will jump out of water is

A

`(sigmah)/(rho)`

B

`((sigma)/(rho)-1)h`

C

h

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
Work done against Buyonancy = gain of gravitational potential energy
`(B-W)h=WH`
`H=((B)/(W)-1)h" "implies H=((sigma)/(rho)-1)h`
