Question

Assertion: In case of motion of an ideal fluid in a horizontal tube, where the area of cross-section is minimum, pressure is maximum. Reason: Hydrostatic pressure in different ideal liquids at points of different depth can be same., If both Assertion and Reason are true and the Reason is correct explanation of the Assertion., If both Assertion and Reason are true but Reason is not explanation of the Assertion., If Assertion is true but the Reason is false., If Assertion is false but Reason is true.

According to the equation of continuity, speed of the fluid is maximum at the minimum cross-sectional area of a horizontal tube and so will be the kinetic energy. And according to Bernoulli's theorem, the pressure will be minimum, where kinetic energy is maximum. So Assertion is false. The reason is true, as excess pressure due to fluid is ρgh . So, for fluids of different densities, pressure can be the same at different depths.
