Solve for part a and b

A small spherical insulator of mass 1.44 x 10-2 kg and charge +0.600 JC is hung by a thin wire of negligible mass. A charge of -0.900 HC is held 0.150 m away from the sphere and directly to the right of it, so the wire makes an angle 0 with the vertical (see the drawing). Find (a) the angle 0 and (b) the tension in the wire. 0.150 m +0.600 UC -0.900 uC (a) Number i Units (b) Number i Units N
