A Small Spherical Insulator Of Mass 800 102 Kg

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 θ with the vertical (see the drawing). Find
(a) The angle θ and
(b) The tension in thethread.A small spherical insulator of mass 8.00 × 10-2 kg
