Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are q1 = 6.15 C, q2 = 1.78 C, and q3 = 1.82 C. Marble q1 is a distance r1 = 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 On the xy coordinate plane there are three charges, all of them along the x axis. The positive charge q_1 is to the left of the origin along the negative x axis a distance r_1 from the origin. The positive charge q_2 is at the origin, with a distance from the origin of r_2=0 m. The negative charge q_3 is to the right of the origin along the positive x axis a distance r_3 from the origin. The observation point is to the left of the origin and to the right of q_1 along the negative x axis a distance r' from the origin, where r' is less than r_1. Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of 3.62 C, calculate magnitude and direction of the force on it. magnitude ______N direction Up, down, left, or right?
