NEET Physics Pressure in Fluids Assertion Reason Question
Assertion (A): At a depth of 1 km in the ocean, the pressure is approximately 100 atm.
Reason (R): The pressure increase in a fluid is directly proportional to the depth and the density of the fluid.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that at a depth of 1 km, the pressure increase is 100 atm, which is explained by the formula P = P_a + ρgh, showing direct proportionality to depth and density.
