Homework Statement
An isolated sphere with charge +q can be treated as a capacitor whose second conductor is a hypothetical (spherical) plane with a ground potential and charge -q, located at a distance infinitely far from the sphere. the capacitance of the isolated conductive sphere is given by: C = 4pi Eo a, where C is the capacitance and a is the radius of the sphere. Calculate the charge q on a conductive sphere with a = 1.9 cm, when it is charged with a charging potential Vc = 6kV. Can you verify this calculation in the experiment? Explain briefly.
Homework Equations
The Attempt at a Solution
q = CV = 1.27 X 10^-8
No? because it is difficult to set up an infinitely far space without noise?
Thanks
