Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are q = 5.90 C, q2 = 1.35 C, and 93 = -1.71 C. Marble q is a distance r = 3.00 cm to the left of the marble q2, while marble q3 is a distance r3 = 2.00 cm to the right of the marble q2, as shown. Calculate the magnitude of the electric field a distance r=1.00 cm to the left of the center marble. N/C observation point -Select-- C 92 93 -72=0m Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of -3.89 C, calculate magnitude and direction of the force on it. magnitude N direction
