Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are q1 = 6.25 µC, q2 = 1.70 µC, and
q3 = −1.66 µC.
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.
Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of
−3.74 µC,
calculate magnitude and direction of the force on it.
