Practice question

Given: What is the dimensional formula of electrical conductance ( G = 1/R ), where R is resistance with SI unit kg m² s^{-3 A^{-2 ? These values define the system as per NCERT data. Formula: [R] = kg m² s^{-3 A^{-2 = [M L² T^{-3 A^{-2]. This is standard NCERT relation. Substitution & Calculation: [G] = 1 / [R] = [M^{-1 L^{-2 T³ A²] . Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
