Question

The R.D. of a metal block is $2.7\times {10}^{3}kg/m^3$. If it is immersed in water, then the block :

• A. sinks
• B. floats
• C. is partially immersed
• D. has no part immersed

Answer 1

The correct option is A sinks

A substance with a density greater than that of water will sink in water and a substance with a density less than that of water will float in water.

Density of water$=1000kg/m^3$

Here Density of substance/block$=2700kg/m^3$

$1000<2700$

Hence the block will sink in water.

Therefore the correct option is (A).
