1.	A spherical ball of radius R is floating at the interface of two liquids with densities `rho` and `2rho`. The volumes of the ball immersed in two liquids are equal. Answer the following questions: Find the force exerted by the liquid with density `2rho` on the ballA. `piR^(2)rhog(H+(2R)/(3))`B. `(2)/(3)piR^(2)rhog`C. `(4)/(3)piR^(2)rhog`D. `2piR^(2)rhog(H+(2R)/(3))`
Answer» Correct Answer - D `piR^(2)2Hrhog+(2)/(3)piR^(3)2rhog=F` `2piR^(2)Hrhog+(4piR^(3)rhog)/(3)=F,2piR^(2)rhog(H+(2R)/(3))=F`
