NEET Physics Physical Quantities Assertion Reason Question
Assertion (A): The dimensions of a physical equation must be consistent on both sides to ensure its validity.
Reason (R): Dimensions of physical quantities can be added or subtracted only if they are the same.
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
Both the assertion and reason are true, and the reason correctly explains that dimensional consistency ensures the validity of equations, as only quantities with identical dimensions can be combined.
