NEET Physics Surface Tension Assertion Reason Question
Assertion (A): A drop of liquid under no external forces is always spherical in shape. | Reason (R): Surface tension acts to minimize the surface area of a liquid drop, leading to a spherical shape.
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.
Correct Answer
Detailed Explanation
The statement that a liquid drop under no external forces is spherical is true because surface tension acts to minimize surface area, which is achieved with a spherical shape.
