5.55 C, 92 = 1.77 C, and 93 = -2.27 C. Marble 91 is a Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are 91 = distance r = 3.00 cm to the left of the marble 92, 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 r' = 1.00 cm to the left of the center marble. N/C + 91 observation point 92 93 2=0m Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of -3.57 C, calculate magnitude and direction of the force on it. magnitude N direction ---Select--- upwards downwards left Additional M right Reading
