In the Figure,a Small Spherical Insulator of Mass 6

Question 17

Multiple Choice

In the figure,a small spherical insulator of mass 6.00 × 10-2 kg and charge +0.400 μC is hung by a thin wire of negligible mass.A charge of -0.220 μC is held 0.290 m away from the sphere and directly to the right of it,so the wire makes an angle θ with the vertical,as shown.What is the angle θ?
