1 Compared to the charge of a proton, the charge of all electron has
(1) a greater magnitude and the same sign
(2) a greater magnitude and the opposite sign
(3) the same magnitude and the same sign
(4) the same magnitude and the opposite sign
The answer is (4). The same magnitude and the opposite sign. For a proton, it has one positive electric charge. And for electron, it has one negative electric charge. So they have same magnitude but opposite sign.
