We have a vessel in shape of a cuboid partially filled with water. It base is square wilth an area of `4.5dm^(2) (1dm=10cm)` and a vessel contains water up to `2 cm` height. Then we place wooden cube inside water. The wood has mass `4kg` and specific gavity `0.5`. The base of the wooden cube is horizontal. Find the height of water level above the base of the wooden block.

A

`10 cm`

B

`2 cm`

C

`15 cm`

D

`7 cm`

Text Solution

Verified by Experts

The correct Answer is:
A
Pressure at A and B will be the same.
`m=a^3rho`
`4=a^3xx500`
`a=1/5`
`P_0+rhogh=P_0+(mg)/A`
`h=10cm`
