5 - Data Analysis: find the charge
Q
Suppose we have a sphere of radius
R
sitting on your desk with an unknown amount of charge Q. The electric field outside the sphere at distances
r
from the center of the sphere is
E=k(Q)/(r^(2)),r>R
A device is use to take measurements of the electric. Suppose we take measurements of the electric field at different
r
as follow \table[[
E((N)/(C))
