APFIVE Comparing Buoyant Forces in Different Fluids
A solid cube of side length $$L$$ and density $$\rho_1$$ is placed in a fluid of density $$\rho_2$$, where $$\rho_1 < \rho_2$$. The cube is then placed in a second fluid of density $$\rho_3$$, where $$\rho_3 = \rho_1/2$$. How does the buoyant force on the cube in the second fluid compare to the buoyant force in the first?
A
It increases to twice its original value
B
It remains the same
C
It decreases to $$\rho_1/(2\rho_2)$$ times its original value
D
It decreases to half its original value
