Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are q1 = 6.20 JC, 92 = 1.37 JC, and q3 = -2.35 JC. Marble q1 is a distance 1 = 3.00 cm to the left of the marble q2, while marble q3 is a distance 3 = 2.00 cm to the right of the marble q2, as shown. Calculate the magnitude of the electric field a distance ' = 1.00 cm to the left of the center marble. N/C X 91 92 2=0m observation point Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of 3.80 JC, calculate magnitude and direction of the force on it. magnitude IN direction ---Select--- v
