A large electroscope is made with "leaves" that are 78 cm longwires with tiny 11 g spheres at the ends. When charged, nearly allthe charge resides on the spheres. If the wires each make a 26°angle with the vertical, what total charge Q must have been appliedto the electroscope? Ignore the mass of the wires.
