A parallel plate capacitor is made of two circular plates separated by a distance of $\displaystyle 5$ mm and with a dielectric of dielectric constant $\displaystyle 2.2$ between them. When the electric field in the dielectric is $\displaystyle 3 \times 10^4 \mathrm{~V} / \mathrm{m}$, the charge density of the positive plate will be close to :
Official answer
(1)
$\displaystyle 6 \times 10^{-7} \mathrm{C} / \mathrm{m}^2$
