In the figure, a small spherical insulator of mass 6.00 x 10-2kg and charge + 0.400 *C is hung by a thin wire of negligible mass. A charge of - 0.220 uC is held 0.290 m away from the sphere and directly to the right of it, so the wire makes an angle 8 with the vertical, as shown. What is the angle 8?
