I have a question, and i don't know how to solve it...

They ask me for the dielectric strength!

How do i find it?

The square plates of a 9000pF capacitor measure 90mm by 90mm and are separated by a dielectric which is 0.29mm thick. The voltage rating of the capacitor is 300V. THe dielectric strength, in KV/m is closest to:

A. 1300

B. 930

C. 1200

D. 1100

E. 1000

To be honest i have no idea how to approach this problem.

[tex]C=\frac{\epsilon_0 A}{d}[/tex] where d=thickness and A=area

Eo = 8.85 x10^-12

A= 8.1x10^-3

d = 2.9x10^-4

so the final answer is C = 2.4719x10^-10

Now what should i do?
