A) 0.9
B) 1.0
C) 1.2
D) 1.5
Correct Answer: D
Solution :
Using the law of buoyancy, we have \[V\sigma g=0.6V{{\sigma }_{1}}g,\]for the part of body outside oil and\[V\sigma g=0.4V{{\sigma }_{2}}g,\]for the part of body outside water, hence we get \[1=\frac{0.6{{\sigma }_{1}}}{0.4{{\sigma }_{2}}}\] So we have, \[\frac{{{\sigma }_{2}}}{{{\sigma }_{1}}}=\frac{6}{4}=\frac{3}{2}\] \[=1.5\]You need to login to perform this action.
