31. For our estimate of V submerged we interpret “almost completely submerged” to mean V submerged 4 3 πr 3 o where r o =60cm . Thus, equilibrium of forces (on the iron sphere) leads to F b = m iron g = ρ water gV submerged = ρ iron g µ 4 3 πr 3 o 4 3 πr 3 i where r i is the inner radius (half the inner diameter).

Unformatted text preview: V submerged as well as the densities of water (1 . 0 g / cm 3 ) and iron (7 . 87 g / cm 3 ), we obtain the inner diameter: 2 r i = 2 r o µ 1 − 1 7 . 87 ¶ 1 / 3 = 57 . 3 cm ....
