Solution

The correct option is B False
If the density of an object is more than the density of a liquid, then it sinks in the liquid. On the other hand, if the density of an object is less than the density of a liquid, then it floats on the surface of the liquid.
Density = $\frac{M a s s}{V o l u m e}$ = $\frac{50}{20}$ =2.5 g/ $c m^{3}$

Hence, The object will sink.
