A ball is attached to a filament of length L = 25.0 cm and suspended from the ceiling, as shown in the figure. A uniform electric field points to the right in the figure. When  ? = 15.5°,  the ball is in equilibrium. Find the net charge on the ball (in µC).   b) What If? If the electric field is suddenly turned off, what is the speed of the ball at the bottom of its swing (in m/s)?
