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