Question

A cylindrical log separates two liquids of denstites p and 3p. FInd'h' Concidering horizontal equilibrium of the cylinder

Answer 1

Explanation:

Torque of hydrostatic force about centre of sphere is already zero as hydrostatic force passes through the centre.

∴FLHS=FRHS

∴12(2ρ)(g)h2=12(3ρ)(g)R2

∴h32−−√R

Answer 2

Torque of hydrostatic force about centre of sphere is already zero as hydrostatic force passes through the centre.

∴FLHS=FRHS

∴12(2ρ)(g)h2=12(3ρ)(g)R2

∴h32−−√R
