## Homework Statement

Two square metal plates with sides of length 0.1 m are separated in vacuum by 10

^{-3}m. Find their capacitance.

## Homework Equations

C = Q/V

For a parallel plate capacitor:

C = E

_{0}A/L

## The Attempt at a Solution

If A is supposed to be the length of the metal plates with 0.1 m, since A has units of m

^{2}, I took A = (.1m)

^{2}= .01 m

^{2}and L = 10

^{-3}m.

From there and plugging everything in, I get:

C = (8.85 x 10

^{-12}C

^{2}/N m

^{2}* .01m

^{2}/10

^{-3}m

C = 8.85 x 10

^{-11}Farads

If someone could confirm whether this is correct or not, I would appreciate it.
