The densit of a block of wood which flots on water with 0.1 of its volume above water is:

A

0.9 g/cc

B

0.9 kg/cc

C

0.1 g/cc

D

0.1 kg/gcc

Text Solution

Verified by Experts

The correct Answer is:
A
For floating bodies
Weight of floating body = welght of liquid displaced or Volume `xx` density of wood = volume of water displaced x density of water Let V be the volume of wood.
Then, volume of wood under water = (1 - 0.1)
`V=0.9V`
`:. VxxD = 0.9V xx1`
or `D=0.9g//"cc"`
