When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. The force between charges varies linearly with the distance between them. What Are Roberts Rules of Order for Meetings? Normal household circuits in the U.S. operate on an AC voltage of about V =120 volts. Charge is a basic property of matter. When a positive charge is brought closer to a negative charge, excess number photons from the positive charge get transferred to the negative charge, so that the number of photons in both the charges are balanced. Positive charges come from having more protons than electrons, and negative charges are a result of having more electrons than protons. Magnets attract when a north pole is introduced to a south pole. When we hold two magnets together so that like or same poles are close together (two north or two south) they repel. Another example are positive ions (cations) moving towards cathode and negative ions (anions) moving towards anode in electrolysis. 2 : . Multiple models may sometimes be used to describe a single phenomena. The three laws of electric charges are that like charges repel, unlike charges attract and that charged objects can be attracted to neutral objects. 2. a proton (positive charge) attracts an electron (negative charge) whereas proton (positive charge) repels another proton (positive charge). New comments cannot be posted and votes cannot be cast. The like charges mean the charges of the same kind and unlike charges mean charges of different kinds. Why do particles attract each other? Whereas opposite or unlike charges attract each other. That product in units appropriate for atomic and nuclear processes is: A negative force implies an attractive force. The choice to use any given model is therefore somewhat arbitrary.

If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. That said, I strongly suspect that there exists no simpler model than the current one, and as such the current model is a good choice from the viewpoint that simplicity is desirable. The term "electric charge" refers to just two types of entities. Therefore, like charges repel and unlike charges attract. I assume that this would be possible (intuitively I feel I could do this to Coulomb's law, for example, without too much difficulty, I may be wrong)? Now, when a positive charge is brought closer to another positive charge, once the virtual transfer of photons occurs, there is an excess number of photons in both the charges, which tend to repel them away from each other. Objects with like charges repel and unlike charges attract. Score: 4.7/5 (31 votes) . Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The simple version: Repulsion and attraction of electrically charged objects is the result of virtual particle exchange (photons), having both momentum and velocity vectors.
