Density and pressure — practice question

A solid is entirely beneath the surface of a liquid. A student finds the ratio $\frac{\text{upthrust acting on the object}}{\text{weight of the object}}$. Which one change would make this ratio twice as large?

  • AUse a different liquid that has twice the density and the same volume as the original liquid.
  • BUse a different object that has half the volume and the same density as the original object.
  • CUse a different object that has twice the density and the same volume as the original object.
  • DUse a different object that has twice the volume and the same density as the original object.
