The dimensional formula for electric flux is $..........$
A$\left[ ML ^3 I ^{-1} T ^{-3}\right]$
B$\left[ M ^2 L ^2 I ^{-1} T ^{-2}\right]$
C$\left[ ML ^3 I ^1 T ^{-3}\right]$
D$\left[ ML ^{-3} I ^{-1} T ^{-3}\right]$
(AIIMS-2015)
Solution
(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 $\left[ ML ^3 T ^{-3} I ^{-1}\right]$
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 $\left[ ML ^3 T ^{-3} I ^{-1}\right]$
