A solid cone of height H and base radius `H/2` floats in a liquid of density `rho`. It is hanging from the ceiling with the help of a string. The force by the fluid on the curved surface of the cone is (`P_(0) =` atmospheric pressure) A. `piH^(2)((P_(0))/4+(rhogH)/3)`B. `piH^(2)((P_(0))/4+(rhogH)/6)`C. `(piH^(2))/4((P_(0))/4+rhogH)`D. `(piH^(2))/4(P_(0)+rhogH)` |

Answer» Correct Answer - B `1/3pi(H/2)^(2)Hrhog=(P_(0)+rhogH)pi(H/2)^(2)-Fv` `F_(v)=P_(0)pi(H^(2))/4+rhog(H^(3))/4pi-(piH^(3)rhog)/12` `=P_(0)(piH^(2))/4+(rhogH^(3)pi)/6` |
