Homework Statement
The charge center of a thundercloud, drifting 3.0km above the Earth's surface, contains 20 C of negative charge.
Assuming the charge center has a radius of 1.0km Calculate the Capacitance of the system.
Homework Equations
C=8.85*(10^(-12))*A/d
Where A is the area, D is the separation distance
The Attempt at a Solution
Basically I just used the formula and plugged and chugged because of the large sizes, we can ignore the curvature and treat it as parallel plate capacitors.
8.85*10^(-12)*4∏(1000)^2/3000
This however gave me the wrong answer, I'm not really sure where to go from here since this path was wrong.
I hope there isn't a limit to how many questions you can ask in a day :P
