Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are 91 - 93 = -1.91 C. Marble q is a distance r = 3.00 cm to the left of the marble 92, while marble q3 is a distance r3 = 2.00 cm to the right of the marble 92, as shown. 5.70 pc, q2 1.43 C, and Calculate the magnitude of the electric field a distance r = 1.00 cm to the left of the center marble. x 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 91 1 43 92 observation point = 0 m Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of -3.55 C, calculate magnitude and direction of the force on it. x magnitude If you know the electric field how do you calculate the force on a charge in that electric field? Did you convert all of your values to SI units (meters, kilograms, coulombs, seconds)? N
