P1.25 H 1.25 Beyond fluids, Archimedes' principle has proven useful in geology when applied to solids on the earth's crust. Figure P1.25 depicts one such case where a lighter conical granite mountain "floats on" a denser basalt layer at the earth's surface. Note that the part of the cone below the surface is formally referred to as a frustum. Develop a steady-state force balance for this case in terms of the fol- lowing parameters: basalt's density (P), granite's density (P), the cone's bottom radius (r), and the height above (h₁) and below (h) the earth's surface.
