Dimensions of physical quantities

Question

Electric displacement is given by $D = ε E,$ Here, $ε =$ electric permittivity
E = electric field strength
The dimensions of electric displacement are

Moderate

A

$[M L^{- 2} T A]$
B

$[L^{- 2} T^{- 1} A]$
C

$[L^{- 2} T A]$
D

None of these

Solution

Electric displacement, $D = ε E$
Unit of D $= \frac{C^{2}}{N m^{2}} \frac{N}{C}$
$[D] = C (\frac{C}{m^{2}}) = \frac{[A T]}{[L^{2}]} = [L^{- 2} T A]$
