In the figure, a small spherical insulator of mass 6.00×10?2kg and charge +0.400?C is hung by a thin wire of negligible mass. A charge of ?0.220?C is held 0.290m away from the sphere and directly to the right of it, so the wire makes an angle ? with the vertical, as shown. What is the angle ? ? (k=1/4??o?=8.99×109N?m2/C2)0.917? (B) 1.50?1.30? (D) 1.70?1.10?
