A cylinder of mass M and density `d_(1)` hanging from a string, is lowered into a vessel of cross-sectional area A, containing a liquid of density `d_(2) (d_(2) lt d_(1))` until it is fully immersed. The increase in pressure at the bottom of the vessel is

Options

A. `(Md_2g)/(d_1A)`
B. `(Mg)/(A)`
C. `(Md_1g)/(d_2A)`
D. zero

Answer

A

Explanation

Increase in pressure
`=("Force exerted by the cylinder on the liquid")/(A)`
`=("Upthrust")/(A) = (Md_2g)/(d_1A)`
