Two small pith balls, each of mass m = 17.4 g, are suspended from the ceiling of the physics lab by 1.2 m long fine strings and are not moving. If the angle which each string makes with the vertical is = 17.9°, and the charges on the two balls are equal, what is the magnitude of that charge (in µC)?
