$1:1$

Vedclass · Answer

(A) The pressure $P$ at a depth $h$ in a liquid of density $\rho$ is given by the formula $P = P_0 + \rho gh$,where $P_0$ is the atmospheric pressure and $g$ is the acceleration due to gravity.Since both membranes are placed at the same depth $h$ in the same liquid,the pressure acting on them depends only on the depth,the density of the liquid,and the atmospheric pressure.Pressure is independent of the surface area of the membrane.Therefore,the ratio of the pressures on the two membranes is $1:1$.

Two stretched membranes of area $2\, cm^2$ and $3\, cm^2$ are placed in a liquid at the same depth. The ratio of pressures on them is
