NEET Physics Pressure in Fluids MCQ Question
Which of the following statements about pressure in fluids is correct?
Pressure in a fluid at rest increases with depth according to the formula P = P_a + ρgh.
The pressure applied to a fluid at rest is transmitted only to the walls of the containing vessel.
The unit of pressure, pascal, is defined as N m.
Pressure in a fluid at rest is not uniform at different heights within the fluid.
Correct Answer
Detailed Explanation
According to Pascal's law, pressure in a fluid at rest is the same at all points at the same height, and pressure increases with depth as given by the equation P = P_a + ρgh. Option B is incorrect because pressure is transmitted throughout the fluid, not just to the walls. Option C is incorrect as the correct definition is N m^-2. Option D is false because pressure in a fluid at rest is uniform at a given height.
