Four particles with the same charge q = 109 C are placed at the vertices of a square with side I = 12 cm. You need to calculate: a) the electric field in the center, O, of the square. b) the potential difference between O and the middle point, M, of the side of the square. c) the work that needs to be done to make the square smaller of side 1/2
