Question

You are provided with a hollow iron ball A of volume 15
cm3 and mass 12 g and a solid iron ball B of mass 12 g
Both are placed on the surface of water contained in a large tub
Find upthrust on each ball Which ball will sink ? Give reason (
Density of iron = 8 0 g cm-3 )

Density of water, Ïw = 1 g/cm3 Let the density of hollow ball be Ï, $ρ = \frac{12}{15} = \frac{4}{5} < ρ_{w} B o d y w i l l f l o a t o n w a t e r U p t h r u s t = m g = 12 \times g = 12 g f$ For solid sphere, $V o l u m e, V' = \frac{12}{8} = \frac{3}{2} {c m}^{3} U p t r u s t = V' ρ_{w} g = \frac{3}{2} \times 1 \times g = 1 5 g f$

You are provided with a hollow iron ball A of volume 15 cm3 and mass 12 g and a solid iron ball B of mass 12 g. Both are placed on the surface of water contained in a large tub. Find upthrust on each ball. Which ball will sink ? Give reason. ( Density of iron = 8.0 g cm-3 )
