Question

The dimensional formula of electric potential is

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

Answer 1

Answer: (A)

Electric potential,
$V=\frac{W}{q}=\frac{\left[M{L}^2{T}^{-2}\right]}{\left[AT\right]}$
$=\left[M{L}^2{T}^{-3}{A}^{-1}\right]$
