The buoyant force on a body is given by Archimedes' principle: $F_b={\rho }_{\mathrm{fluid}}\times g\times V_{\mathrm{displaced}}$. This force depends directly on the density (ρ) of the fluid. Since different fluids have different densities (e.g., water vs. oil), the buoyant force acting on the same submerged body will be different for each fluid.

Final Answer: different
