On the other hand, a positive charge requires electrons to become neutral, that is why it moves towards negative charge. The attraction or repulsion acts along the line between the two charges. What causes electrical charges to attract and repel? Like charges repel each other; unlike charges attract. 2 : . Therefore, like charges repel and unlike charges attract. Answer: By an intermolecular force known as the intermolecular force of attraction, particles of matter are attracted to one another. The density of metallic copper is about 9 grams/cm3 and one mole of copper is 63.5 grams so the cubic centimeter of copper contains about 1/7th of a mole or about 8.5 x 1022 copper atoms. This allows the electric charges to move within the conductor and also be easily transferred to another material. 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)? 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. 2 : to become weary or satiated. Coulomb's law, (1) first published in 1784 by French physicist Charles de Coulomb, is one of the most fundamental laws of science that describes the electrostatic interaction between electrically charged particles. If this is the case, our concept of charges is somewhat arbitrary. 1. That product in units appropriate for atomic and nuclear processes is: A negative force implies an attractive force. If two such charges could indeed be concentrated at two points a meter apart, they would move away from each other under the influence of this enormous force, even if they had to rip themselves out of solid steel to do so! Ohm's Law Positive charges come from having more protons than electrons, and negative charges are a result of having more electrons than protons. In Coulomb's law however the magnitude and sign of the electric force are determined by the electric charge rather than the mass of an object. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. Suppose you were to graph F as a function of r for two positive charges Advertisement Muscardinus New comments cannot be posted and votes cannot be cast. Charge is a basic property of matter.
