The fundamental physics quantities which form the basis for the MKS system are:
Correct answer: B. Mass, length and time
- A. Force, weight and time
- B. Mass, length and time
- C. Mass, length and force
- D. Mass, energy and time
Explanation
B is the correct answer. The MKS system is based on three fundamental units: mass (kilogram), length (meter), and time (second). These three quantities form the foundation for measuring other physical quantities in the MKS system.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
