A) \[0.6\text{ }g\text{ }c{{m}^{-3}}\]
B) \[1.0\text{ }g\text{ }c{{m}^{-3}}\]
C) \[0.4\text{ }gc{{m}^{-3}}\]
D) \[0.24\text{ }gc{{m}^{-3}}\]
E) none of these
Correct Answer: A
Solution :
\[\frac{Volume\text{ }of\text{ }cube\text{ }submerged}{Total\text{ }volume}\] \[=\frac{density\text{ }of\text{ }cube\text{ }material}{density\text{ }of\text{ }water}\] \[\Rightarrow \] \[\frac{10-4}{10}=\frac{d}{1}\] \[\therefore \] \[d=\frac{6}{10}=0.6g\,c{{m}^{-3}}\]
