NEET Physics Physical Quantities Assertion Reason Question
Assertion (A): Only physical quantities with the same dimensions can be added or subtracted.
Reason (R): Units of derived quantities are always combinations of base units.
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.
