Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are 91 = 7.00 C, 92 = 1.49 C, and 93 = -1.88 C. Marble 91 is a distance r = 3.00 cm to the left of the marble q, while marble q3 is a distance r3 = 2.00 cm to the right of the marble 92, as shown. Calculate the magnitude of the electric field a distance the left of the center marble. = 1.00 cm to N/C 13 92 93 91 observation point r =0m Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of 3.58 C, calculate magnitude and direction of the force on it. magnitude N direction right
