$E$ Field in Capacitor

APPHEM-NPJYAX

A parallel plate capacitor is made from a square conductor with sides that are $0.3\ \text{m}$ in length. The separation distance between the plates is $0.05\ \text{m}$. A $10$-volt battery is put across the capacitor. What is the strength of the electric field in between the plates after the capacitor has time to charge?

A

$0.3\ \text{V/m}$

B

$0.5\ \text{V/m}$

C

$200\ \text{V/m}$

D

$333\ \text{V/m}$

E

$400\ \text{V/m}$
