MCQ
The dimensional formula for electric flux is $..........$
  • $\left[ ML ^3 I ^{-1} T ^{-3}\right]$
  • B
    $\left[ M ^2 L ^2 I ^{-1} T ^{-2}\right]$
  • C
    $\left[ ML ^3 I ^1 T ^{-3}\right]$
  • D
    $\left[ ML ^{-3} I ^{-1} T ^{-3}\right]$

Answer

Correct option: A.
$\left[ ML ^3 I ^{-1} T ^{-3}\right]$
a
(a)

The unit of electric field is $Vm$.

Hence dimension of electric field is $\left[ MLT ^{-3} I ^{-1}\right]$

The electric flux is given in unit $Nm ^2 C ^{-1}$

Hence dimension of electric flux is $\left[ ML ^3 T ^{-3} I ^{-1}\right]$
