A large electroscope is made with "leaves" that are 78 cm long wires with tiny 17g spheres at the ends. When charged, nearly all the charge resides on the spheres.

Part A If the wires each make a 30 degree angle with the vertical, what total charge Q must have been applied to the electroscope? Ignore the mass of the wires.
