A solid cone of height H and base radius...

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)

Text Solution

Verified by Experts

There will be only vertically downard force on the curved surface of the cone as the horizontal force will be cancelled. Let this force be F
Buoyoney force =`(P_(0)+SgH)piR^(2)-F`
`1//3piR^(2)HSg=(P_(0)+SgH)piR^(2)-F`
`F=(piR^(2))/(3)(3P_(0)+2SgH)`
