NEET Physics Pressure in Fluids Assertion Reason Question
Assertion (A): When a fluid is at rest, the force it exerts on a submerged object is always perpendicular to the object's surface. | Reason (R): Any parallel component of force would cause the fluid to move, contradicting the condition of the fluid being at rest.
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 explains that if a fluid at rest had a parallel force component, it would flow, which cannot happen when the fluid is static. Thus, the force must be perpendicular.
