A-LevelPhysicsForces, density and pressureOct/Nov 2023Paper 1 Q141 Mark
Two solid cylindrical objects X and Y are held fully submerged in a liquid, as shown. [Figure 14.1] The objects have the same volume. The density of the material of Y is twice the density of the material of X. Both objects are stationary. Which statement is correct?
AThe force due to the liquid acting on the top surface of X is greater than that acting on the top surface of Y.
BThe pressure difference due to the liquid between the top and bottom surfaces of X is the same as that for Y.
CThe upthrust acting on X is the same as the upthrust acting on Y.
DThe weight of X is the same as the weight of Y.
