Question 1:(20 pts) d 9: 92 93 > Three charged objects with charges 91, 92, and qz are placed on the x-axis as seen in the figure above. The location of q, is fixed at the origin while the object with charge q, has a fixed location at d. The object with charge qz is at a point x in the positive direction of x axis. For q = 49,92 = -9,43 =-9,9=1C and d=1m: (a) If 9; is placed at x = = 3d , what is the magnitude of the electrostatic force on 93? (b) If 93, initially fixed at x = 3d, is released and free to move, in what direction of the x-axis will it start moving and why? (c) At which points on the x-axis is the net electrostatic force on q3 is zero? Show these points on the x-axis. = >
