NEET Physics Physical Quantities MCQ Question
Which of the following combinations about physical quantities are correct?
Base quantities are independent and have their own units; derived quantities depend on base quantities.
All physical quantities can be expressed as derived quantities; base quantities are just a subset.
Units of derived quantities are always the same as base units; dimensional analysis is only for base quantities.
Base quantities include length, mass, time, and derived quantities cannot have independent units.
Correct Answer
Detailed Explanation
Base quantities are defined independently with their own units, while derived quantities are expressed as combinations of these base units. This aligns with the definition of physical quantities in the NCERT context.
