Two charged beads are on the plastic ring in Figure (a). Bead 2, which is not shown, is fixed in place on the ring, which has radius R = 62.6 cm. Bead 1 is initially on the x axis at angle = 0°. It is then moved to the opposite side, at angle 0 = 180°, through the first and second quadrants of the xy coordinate system. Figure (b) gives the x component of the net electric field produced at the origin by the two beads as a function of 0, and Figure (c) below gives the y component. The vertical axis scales are set by Exs = 5.85 x 104 N/C and Eys = -10.53 × 104 N/C. (a) At what positive angle is bead 2 located? (Note: bead 2 is negative charged). What are the charges of (b) bead 1 and (c) bead 2? (a) Number (b) Number i (a) J R 8 (b) Exs -Exs IAN 90° 180° Units -Ring Units -Bead 1 x (c) Eys 90° 180° 8
