In the Figure, a Small Spherical Insulator of Mass 6

question 19

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? (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)

• A) 0.917°
• B) 1.10°
• C) 1.30°
• D) 1.50°
• E) 1.70°
