Dimensional formula for surface charge density is

The correct answer is Option (2) → \( [M^{0}L^{-2}TA] \)

Surface charge density is charge per unit area, \( \sigma = Q/A \), and charge is current multiplied by time, \( Q = It \).

    \( [Q] = [\mathrm{A\,T}] \)
    \( [A] = [\mathrm{L^{2}}] \)

    \( \displaystyle [\sigma] = \frac{[\mathrm{AT}]}{[\mathrm{L^{2}}]} = [M^{0}L^{-2}TA] \)

Note: This question is from beyond the NCERT textbook and it appears to be out of the CUET 2026 Physics syllabus.
