A parallel plate capacitor is made of two circular plates separated by a distance 5mm and with a dielectric of dielectric constant 2.2 between them. When the electric field in the dielectric is `3xx10^4V//m` the charge density of the positive plate will be close to:

`6xx10^(-7)C//m^(2)`

`3xx10^(-7)C//m^(2)`

`3xx10^(4)C//m^(2)`

`6xx10^(4)C//m^(2)`
