A small spherical insulator of mass 8.00 × 10-2 kg and charge +0.600 µC is hung by a thread of negligible mass. A charge of - 0.900 µC is held 0.150 m away from the sphere and directly to the right of it, so the thread makes an angle u with the vertical (see the drawing). Find (a) the angle u and (b) the tension in the thread.
