A cylinder of mass and material density \(\rho\) hanging from a string is lowered into a vessel of cross-sectional area A containing a liquid of density \(\sigma( < \rho)\) until it is fully immersed. The increase in pressure at the bottom of the vessel is
- A Zero
- B \(\frac{\mathrm{mg}}{\mathrm{A}}\)
- C \(\frac{m g \rho}{\sigma \mathrm{A}}\)
- D \(\frac{\mathrm{m} \sigma \mathrm{g}}{\rho \mathrm{A}}\)
Answer & Solution
Correct Answer
(D) \(\frac{\mathrm{m} \sigma \mathrm{g}}{\rho \mathrm{A}}\)
Step-by-step Solution
Detailed explanation
From newton third law, excess force acting on the liquid is equal to force of buoyancy acting on the cylinder. The increase in pressure…
