In the figure, a small spherical insulator of mass 6.00 × 10^-2kg 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? (k = 1/4πε0 = 8.99 × 10⁹ N ∙ m²/C²)
