Question

Consider two tubes filled with water at the same height, one with fresh water and the other tube with salt water. The pressure is greater at the bottom of the tube with:
A.) fresh water
B.) salt water
C.) both the same
D.) depends on whether the tubes have the same cross-sectional area

Answer 1

Answer:

B

Explanation:

The correct option for the question is B that is salt water. In salt water, the density of water is higher so the pressure at the end of tube containing salt water will be greater. As according to the hydrostatic law the pressure at a given point will be directly proportional to the distance travelled as well.
