NEET PHYSICSUNITS AND MEASUREMENTSEasy

Question

Which of the following system of units is not based on units of mass, length and time alone?

A

SI

B

MKS

C

FPS

D

CGS

Step-by-Step Solution

  1. Analyze the Systems:
  • CGS: Based on Centimetre (Length), Gram (Mass), and Second (Time) .
  • FPS: Based on Foot (Length), Pound (Mass), and Second (Time) .
  • MKS: Based on Metre (Length), Kilogram (Mass), and Second (Time) .
  • SI: The International System of Units is based on seven base units. Besides units for length, mass, and time, it includes units for electric current (ampere), thermodynamic temperature (kelvin), amount of substance (mole), and luminous intensity (candela) .
  1. Conclusion: The SI system is not based on mass, length, and time alone, as it incorporates electromagnetic, thermodynamic, and other physical quantities defined by seven fundamental units.
