If Q denote the charge on the plate of a capacitor of
capacitance C then the dimensional formula for

\frac{{{Q^2}}}{C}

View answer and explanation

Correct option: C

\left[ {{L^2}M{T^{ - 2}}} \right]

Option C ([L²MT⁻²]) is correct because Q²/C represents energy stored in a capacitor, which has the same dimensions as energy (ML²T⁻²).
