A) \[{{\left( \frac{\rho +{{\sigma }_{2}}}{{{\sigma }_{1}}+{{\sigma }_{2}}} \right)}^{1/3}}\]
B) \[{{\left( \frac{\rho -{{\sigma }_{2}}}{{{\sigma }_{1}}-{{\sigma }_{2}}} \right)}^{1/3}}\]
C) \[{{\left( \frac{\rho -{{\sigma }_{2}}}{{{\sigma }_{1}}+{{\sigma }_{2}}} \right)}^{1/2}}\]
D) \[{{\left( \frac{\rho -{{\sigma }_{2}}}{{{\sigma }_{1}}-{{\sigma }_{2}}} \right)}^{1/2}}\]
Correct Answer: B
Solution :
[b] \[VAB\] is the given cone. Let its height be h and semi-vertical angle a. Let the base AB of the cone be in the surface. CD is the surface of separation of two liquids, O and O? are the centres of the base AB and surface of separation CD.You need to login to perform this action.
