A) \[10.9\,gm\,/c.c.\]
B) \[\frac{9}{4}gm\,/c.c.\]
C) \[\frac{8}{3}gm\,/c.c.\]
D) \[\frac{3}{8}gm\,/c.c.\]
Correct Answer: C
Solution :
\[\frac{\text{Relative}\,\text{density}\,\text{of}\,\text{body}}{\text{Relative}\,\text{density}\,\text{of}\,\text{water}}\] \[\text{=}\frac{\text{volume}\,\text{of}\,\text{inserted}\,\text{part}\,\text{of}\,\text{body}}{\text{total}\,\text{volume}\,\text{of}\,\text{body}}\] \[\frac{d}{1}=\frac{2V}{3V}\] \[\Rightarrow \] \[d=\frac{2}{3}\] Again using the same formula \[\frac{1}{4}=\frac{2}{3d}\] \[\therefore \] \[d=\frac{8}{3}gm/c.c.\]You need to login to perform this action.
