Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of -2.0 JC; sphere B carries a charge of -6.0 JC; and sphere C carries a charge of +4.0 UC. Spheres A and B are touched together and then separated. Spheres B and C are then touched and separated. Does sphere C end up with an excess or a deficiency of electrons and how many electrons is it? O deficiency, 6 x 1013 O deficiency, 3 x 1012 O excess, 2 x 1013 O There is no excess or deficiency of electrons. O excess, 3 x 1013A -4.0-|JC charge is located 0.45 m to the left of a +6.0-IJC charge. What is the magnitude and direction ofthe electrostatic force on the positive charge? 0 1.1 N, to the left 0 2.2 N, to the right 0 2.2 N, to the left 0 1.1 N, to the right 0 4.4 N, to the right A circular loop of wire with a diameter of 0.626 m is rotated in a uniform electric field to a position where the electric flux through the loop is a maximum. At this position, the electric flux is 7.50 x 105 N.m2/C. Determine the magnitude of the electric field. O 8.88 x 105 N/C O 2.44 x 106 N/C O 6.00 x 106 N/C O 1.07 x 106 N/C O 4.24 x 106 N/C
