# (Solved): Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. ...

Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are q1 = 6.65 µC, q2 = 1.65 µC, and q3 = −1.96 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. 285,900,000 Incorrect: Your answer is incorrect. What is the electric field due to each individual marble? How do you find the total or "net" electric field when you have several electric fields? 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 −3.89 µC, calculate magnitude and direction of the force on it.
