medium MCQ Class 11 · Physics · Motion in a Straight Line
  1. Standard SI derived units defined by international physical constants for Motion in a Straight Line
  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 Motion in a Straight Line

The correct answer is Standard SI derived units defined by international physical constants for Motion in a Straight Line — 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 Motion in a Straight Line.
  2. The dimensional formula confirms consistency across both sides of the field equations.
