Here there is a charge of q mass m placed at a distance d from the center a R-fingered conductor ball buried. By using image charge technique, specify: (3) System electrostatic energy! (4) If initially q is at a distance of d = 2R and the charge is given speed v to the right, specify the position of the charge q at the time q stops!
