A block of ice of total area `A` and thickness `0.5m` is floating in water. In order to just support a man of mass `100kg`, the area `A` should be (the specific gravity of ice is 0.9)

A

`2.2m^(2)`

B

`1.0m^(2)`

C

`0.02m^(2)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
Total weight=total upthrust
`(Axx0.5xx900)g+(100)g=Axx0.5xx1000xxg`
`:. A=2m^(2)`.
