In a uniform U-tube containing water, if a liquid of density \(800\ \mathrm{kg\,m^{-3}}\) is poured into one of its limbs to a height of \(25\) cm, then the rise in water level in the other limb of the tube is
Show Hint
In a uniform U-tube, if one side rises by \(x\), the other side falls by \(x\). Hence, the pressure balance is
\[
\boxed{\rho_1h=\rho_2(2x).}
\]
