A small spherical insulator of mass 8.00*10-2 kgandcharge +0.600μC is hung by a thin wire of negligiblemass. Acharge of -0.900μC is held 0.150m away from thesphere and directlyto the right of it, so the wire makes an angleθ with the vertical(see the drawing). Find a)the angle θand b) the tension in thewire.
