NEET Physics Pressure in Fluids MCQ Question
In the diagram shown above, which of the following correctly represents the relationship between atmospheric pressure (P_a), absolute pressure (P), and gauge pressure (P_g) at a certain depth in a fluid?
P = P_a + P_g
P_g = P - P_a
P_a = P - P_g
P = P_g - P_a
Correct Answer
Detailed Explanation
Gauge pressure (P_g) is the difference between the absolute pressure (P) and atmospheric pressure (P_a), as defined in the context.
