A solid copper sphere has a radius of R and holds a net charge
of +Q.
You measure outward a distance of D from the center of the
sphere.
(assume D>R)
You measure the magnitude of the electric field at distance
D.
You then measure out to a distance of 3D from the center of the
sphere and measure again.
How does the magnitude of the electric field at distance 3D
compare to that of D?
