1. The problem statement, all variables and given/known data Two square metal plates with sides of length 0.1 m are separated in vacuum by 10-3 m. Find their capacitance. 2. Relevant equations C = Q/V For a parallel plate capacitor: C = E0A/L 3. 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.
