(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Consider earth and a cloud layer 700m above earth to be the plates of a parallel-plate capacitor. If the cloud layer has an area of 1.9 km^2, what is the capacitance?

2. Relevant equations

Q = CV

V = Ed

E = Q/epsiolon*A

3. The attempt at a solution

Solving for C gives us C=Q/V. Substituting Ed for V gives us C=Q/Ed. Substituting Q/epsilon*A gives us C = epsilon*A/d. Now I just plug in numbers and I should get the value for C, right? I'm putting in the values given but I am not getting the right answer...any suggestions? Thanks in advance to anyone who helps.
