Density and pressure — practice question

A uniform cylinder with weight $25.0\,\text{N}$ is hanging from a newton meter. The cylinder is completely immersed in water, as shown. The newton meter shows a reading of $10.0\,\text{N}$. The water is then changed to a liquid whose density is $10\%$ greater than the density of water. The cylinder is still completely submerged. What reading will the newton meter now show?

  • A$8.5\,\text{N}$
  • B$9.0\,\text{N}$
  • C$11.0\,\text{N}$
  • D$11.5\,\text{N}$
