(1) A small spherical insulator of mass 8 .00 x 102 kg and charge +0.600 \"C is hung by a thread of negligible mass. A charge of 0.900 uC is held 0.150 m away from the sphere and directly to the right of it, so the thread makes an angle 6 with the vertical (see the drawing). Find (a) the angle 6 and (b) the tension in the thread. +0.600 ,th 0.900 ,uC
