An electrically neutral object is given a positive charge. (a) In principle, does the object's mass increase, decrease, or stay the same as a result of being charged? (b) Choose the best explanation from among the following: I. To give the object a positive charge we must remove some of its electrons; this will reduce its mass. II. Since electric charges have mass, giving the object a positive charge will increase its mass. III. Charge is conserved, and therefore the mass of the object will remain the same.
An electrically neutral object is given a negative charge. (a) In principle, does the object's mass increase, decrease, or stay the same as a result of being charged? (b) Choose the best explanation from among the following: I. To give the object a negative charge we must give it more electrons, and this will increase its mass. II. A positive charge increases an object's mass; a negative charge decreases its mass. III. Charge is conserved, and therefore the mass of the object will remain the same.
Does the electric potential increase or decrease as we move toward a negative charge? Explain.
