The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved. A neutral object will attract both a positive and a negative charge. When two materials are in contact, electrons may move from one material to the other, which leaves an excess of positive charge on one material, and an equal negative charge on the other. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. But here, it is the excess number of electrons, which causes repulsion among the two negative charges. Therefore, like charges repel and unlike charges attract. The interaction between two oppositely charged objects is attractive. The reason that like charges repel and opposite charges attract is because of the way that they interact with each other. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. Also Read: Why Does Static Charge Build Up?

Thus, two negative charges repel one another, while a positive charge attracts a negative charge. These two pushing forces have equal magnitudes and are exerted in opposite directions of each other. electrons, they take on a negative charge because each atom now has more electrons than protons. The reason that the balloon will stick to the wall is because the negative charges in the balloon will make the electrons in the wall move to the other side of their atoms (like charges repel) and this leaves the surface of the wall positively charged. It's best to ask how, not why when it comes to elementary level physics. 6 What are negative charges attracted to? When a positive charge is brought closer to a negative charge, excess number protons from the positive charge get transferred to the negative charge, so that the number of protons in both the charges is balanced. Note that this explanation ignores a host of other things: Kinetic Energy (which is positive and decreases as we move further away from the nucleus), Electron-Electron repulsion etc. The cookie is used to store the user consent for the cookies in the category "Other.
