Question 21 POST_UTME_CRAWFORD_UNIVERSITY • 2022 • PHYSICS • objective

A uniform solid sphere of radius R and density ρ is floating in a liquid of density σ. The sphere is in equilibrium, and the pressure at the bottom of the sphere is P. The pressure at the top of the sphere is P + ΔP. U\sing the equation of hydrostatic pressure, derive an expression for ΔP in terms of R, ρ, σ, and g.

Answer Options

Correct Answer A. ΔP = ρg\( 4/3πR^3 - 4/3πR^3\( ρ/σ \ \))
B. ΔP = ρg\( 4/3πR^3 - 4/3πR^3\( σ/ρ \ \))
C. ΔP = ρg\( 4/3πR^3 - 4/3πR^3\( ρ/σ \ \)) + ρg\( 4/3πR^3 \)
D. ΔP = ρg\( 4/3πR^3 - 4/3πR^3\( ρ/σ \ \)) - ρg\( 4/3πR^3 \)
Correct Answer
A
Correct Option:
ΔP = ρg\( 4/3πR^3 - 4/3πR^3\( ρ/σ \ \))
