Two large thin metal plates are parallel and close to each other. On their inner faces, the plates have surface charge densities of opposite signs and magnitude `27xx10^(-22)Cm^(-2)`. The electric field `vecE` in region II in between the plates is
A. `4.25xx10^(-8)NC^(-1)`
B. `6.28xx10^(-10)NC^(-1)`
C. `3.05xx10^(-10)NC^(-1)`
D. `5.03xx10^(-10)NC^(-1)`
