CAIE A-Level Physics AS 4.3.6 The Upthrust Acting on an Object in a Fluid Using the Equation F Gv Questions question 1
Two solid cylindrical objects X and Y are held fully submerged in a liquid, as shown.
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?
A
The force due to the liquid acting on the top surface of X is greater than that acting on the top surface of Y.
B
The pressure difference due to the liquid between the top and bottom surfaces of X is the same as that for Y .
C
The upthrust acting on X is the same as the upthrust acting on Y .
D
The weight of X is the same as the weight of Y.
