NEET Physics Physical Quantities MCQ Question
Which of the following combinations about physical quantities and their dimensions is correct?
A physical quantity can only be expressed in terms of base units; derived units are not valid measures.
All physical quantities can be expressed as combinations of base and derived units; dimensions help in verifying equations.

Only fundamental quantities have dimensions, while derived quantities do not require dimensional analysis.
Correct Answer
Detailed Explanation
Option B is correct as it aligns with the NCERT context that states physical quantities can be expressed as combinations of base and derived units, and dimensions are essential for verifying the consistency of equations.
