Question 894: Electrostats & Capacitance

Question

Which of the following is the dimensional formula for electric polarisation?

Accepted Answer

Electric polarisation $(P)$ is given by
$$P=\varepsilon_0 \chi E$$
where, $E$ is electric field and $\chi$ is electric susceptibility and it is dimensionless quantity,
Dimensional formula of $P=$ Dimensional formula of $\left(\varepsilon_0ight) 	imes$ Dimensional formula of $E$
$$=\left[M^{-1} L^{-3} T^4 I^2ight]\left[M L T^{-3} I^{-1}ight]=\left[M^0 L^{-2} T^1 I^1ight]$$

Answer

$\left[M^P L^{-2} T^1 I^1\right]$

Answer

$\left[M^{-1} L^{-2} T^1 I^{-1}\right]$

Answer

$\left[M^P L^{-1} T^{-1} I^1\right]$

Answer

$\left[M^1 L^{-2} T^1 I^1\right]$
