Question

The dimensional formula for electric flux is

• A. $[M{L}^2{T}^2]$
• B. $[M{L}^3{T}^{-3}{A}^{-1}]$
• C. $[M{L}^{-3}{T}^3{A}^1]$
• D. $[M{L}^{-1}{T}^3{A}^{-2}]$

Answer 1

Answer: (B)

Electric flux, $\varphi =\vec{E}.\vec{s}$
Taking dimensions both side, we get
$[\varphi ]=[ML{T}^{-3}{A}^{-1}][L^2]=[M{L}^3{T}^{-3}{A}^{-1}]$
