NEET Physics Physical Quantities Assertion Reason Question
Assertion (A): Dimensional analysis can determine if a physical equation is dimensionally valid.
Reason (R): Dimensional analysis can provide the exact numerical constants in a physical relationship.
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
Dimensional analysis can test the dimensional validity of equations (A is true), but it cannot provide exact numerical constants (R is false).
