(a) A sphere is attached to a thread of length L = 18.1 cm and suspended from the ceiling, as shown in the figure. A uniform electric field points to the right in the figure. When 0 = 13.0°, the sphere is in equilibrium. Find the net charge on the sphere (in µC). μC E 1.00 × 10³ N/C L m= = 2.00 g g (b) What If? If the electric field is suddenly turned off, what is the speed of the sphere at the bottom of its swing (in m/s)? m/s (a) A sphere is attached to a thread of length L = 18.1 cm and suspended from the ceiling, as shown in the figure.
