Four point charges of equal value q, two positive and two negative, are placed in the vertices of a square with side 2a lying in the plane yz. Calculate the force exerted by the other three charges on the charge +q placed in the vertex (a, a) and the expressions of the potential and of the electrostatic field along the x-axis. Show that at great distances the electrostatic field on the x-axis coincides with that of a moment dipole p = 4qau, placed in the center of the square. 2/40
