A) 0.6 g \[c{{m}^{-3}}\]
B) 1.0 g\[c{{m}^{-3}}\]
C) 0.4 g \[c{{m}^{-3}}\]
D) 0.24 g \[c{{m}^{-3}}\]
Correct Answer: A
Solution :
\[\frac{\text{Volume}\,\,\text{of}\,\,\text{cube}\,\,\text{submerged}}{\text{Total}\,\,\text{Volume}}\] \[\text{=}\frac{\text{density}\,\,\text{of}\,\,\text{cube}\,\,\text{material}}{\text{density}\,\,\text{of}\,\,\text{water}}\] \[\Rightarrow \] \[\frac{10-4}{10}=\frac{d}{1}\] \[\therefore \] \[d=\frac{6}{10}=0.6\,\,gc{{m}^{-3}}\]
