What is the SI unit and dimensional formula for the key physical quantity studied in 'Electric Charges and Fields'?

medium MCQ Class 12 · Physics · Electric Charges and Fields
  1. Standard SI derived units defined by international physical constants for Electric Charges and Fields
  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 Electric Charges and Fields

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