A cubical block of side 10cm floats at the interface of an oil and water as shown in the figure. The density of oil is `0.6g cm^(-3)` and the lower face of ice cube is 2cm below the interface. The pressure above that of the atomosphere at the lower face of the block is

`200Pa`

`620Pa`

`900Pa`

`800Pa`

Text Solution

Verified by Experts

The correct Answer is:

`Delta p=rho_(oil)+g h_(oil)+rho_(w)gh_(w)`
`=(600)(10)(10xx10^(-2))+(1000xx10xx2xx10^(-2))`
`=800N//m^(2)`.
