Question

A cone of radius R and height H, is hanging inside a liquid of density ρ by means of a string as shown in the figure. The force, due to the liquid acting on the slant surface of the cone is, ρ π g H R 2, π ρ H R 2, 4 3 π ρ g H R 2, 2 3 π ρ g H R 2

MARKS App · Accepted Answer

Buoyoncy = force on base-force on slant surface (f ​y ) Force on slant surface = force on base-buoyancy Force on slant surface = π R 2 H ρ g - 1 3 π R 2 H ρ g Force on slant surface = 2 3 π R 2 H ρ g
