Two square metal plates with sides of length 0.1 m are separated in vacuum by 10-3 m. Find their capacitance.
C = Q/V
For a parallel plate capacitor:
C = E0A/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 m2, I took A = (.1m)2 = .01 m2 and L = 10-3 m.
From there and plugging everything in, I get:
C = (8.85 x 10-12 C2/N m2 * .01m2/10-3 m
C = 8.85 x 10-11 Farads
If someone could confirm whether this is correct or not, I would appreciate it.
