Problem 64GP

A large electroscope is made with “leaves” that are 78-cm-long wires with tiny 24-g spheres at the ends. When charged, nearly all the charge resides on the spheres. If the wires each make a 30° angle with the vertical (Figure 16–64), what total charge Q must have been applied to the electroscope? Ignore the mass of the wires.
