Abstract: We calculate the Coulomb forces of the uniformly charged linear body and the conductor flat connecting with earth or the electric conductor ball reaction with the mirror image method in the electromagnetic theory.The superposition principle and mathematical software“Mathematica” can be used,thus the Coulomb forces of the image changing with angle and distance are given.
