Concept

Problem: An electrically neutral object is given a positive charge. In principle, does the object's mass increase, decrease, or stay the same as a result of being charged?a) stay the sameb) decreasec) increaseChoose the best explanation from among the following:a) To give the object a positive charge we must remove some of its electrons; this will reduce its mass.b) Charge is conserved, and therefore the mass of the object will remain the same.c) Since electric charges have mass, giving the object a positive charge will increase its mass.
