Solution Summary

The solution discusses the electric field of three charges.

Solution Preview

The electric field of a point or an exactly spherical charge Q at displacement r(vector) from it is

E(vector) = Q/(4 pi e_0) r(vector) / r^2

that is it is directed away from the charge if Q is positive and towards the charge if Q is negative, and its magnitude is

|E| = |Q|/(4 pi e_0 |r|),

where e_0 ~= 8.85x10^{-12} F/m is the electric permeability of vacuum.

Let us calculate the fields of charges +3.00 microC ...
