A balloon is charged with static electricity until it has a voltage of V = 1300 V. A student reaches out and is shocked by a spark. The electric force does W = 1 x 10-7 J of work transferring the charge.
Part (a) Input an expression for the magnitude of charge transferred Q.
Part (b) What is the charge in C?
Part (c) How many electrons is this?
