Part A.) What is the total negative charge, in coulombs, of all the electrons in a small 1.15 g sphere of carbon? One mole of C is 12.0 g , and each atom contains 6 protons and 6 electrons. Express your answer using three significant figures.

Part B.) Suppose you could take out all the electrons and hold them in one hand, while in the other hand you hold what is left of the original sphere. If you hold your hands 1.50 m apart at arm's length, what force will each of them feel? Express your answer in newtons to three significant figures.

Part C.) Will it be attractive or repulsive?
