Problem 1P
CE Predict/Explain 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.

ANSWER:
Step 1 of 2
(a)
Here we need to comment whether the mass of the object increases, decreases or remains same when a neutral object is given a positive charge.
When a neutral object is given a positive charge, during the process an electron is removed from the neutral object. Since the electron has mass, the resultant positive charged object will has lesser mass compared to the mass of the object when it was neutral.
