STANDARD Physics Hydrostatic Pressure MCQ Question
Type: MCQ-conceptual-Medium
Three vessels A, B and C of different shapes contain a water upto the same height as shown in the figure. Pₐ, P_b and P_c be the pressure exerted by the water at the bottom of the vessels A, B and C respectively. Then
A
Pₐ > P_b > P_c
B
P_b > P_c > Pₐ
C
P_c > P_b > Pₐ
D
Pₐ = P_b = P_c
Correct Answer
Option D
Detailed Explanation
Pressure = hρg. Pressure at the bottom is independent of the area of the base of the vessel. It depends on the height of water upto which the vessel is filled with water. As in all the three vessels, level of water are the same, therefore pressure at the bottom in all the vessels is also the same. Hence, Pₐ = P_b = P_c.
