medium MCQ Class 11 · Physics · Work Energy and Power
  1. Standard SI derived units defined by international physical constants for Work Energy and Power
  2. Dimensionless scalar ratio without base units
  3. Arbitrary empirical units without dimensional consistency
  4. Gravitational units only
Answer
Standard SI derived units defined by international physical constants for Work Energy and Power

The correct answer is Standard SI derived units defined by international physical constants for Work Energy and Power — The dimensional formula confirms consistency across both sides of the field equations.

Step-by-step solution

  1. Dimensional analysis converts base SI quantities (M, L, T, A) into the derived unit for Work Energy and Power.
  2. The dimensional formula confirms consistency across both sides of the field equations.
