1. Pith Ball Electroscope (10 marks) Two 4.5 g pith balls are connected to massless strings and suspended from a support. They are then given equal charges, The result is shown in the diagram. Assume the diagram is the actual size. . Show all key measurements on the diagram. . Sketch a complete force diagram of the left pith ball. There are three forces. . Determine the electric force on the left pith ball using the principles of physics . Determine the magnitude of each charge
