The electric charge of one electron is equal in magnitude and opposite in sign to the charge of one proton. An ion is an atom or molecule that has nonzero total charge due to having unequal numbers of electrons and protons.

- 7.4: Calculations of Electric Potential
Calculate the potential of a continuous charge distribution. Point charges, such as electrons, are among the fundamental building blocks of matter. Furthermore, spherical charge distributions (such as charge on a metal sphere) create external electric fields exactly like a point charge.
An electrical charge distributes itself equally between two conducting spheres of the same size. Knowing this allowed Coulomb to divide an unknown charge in half. Repeating this process would produce a sphere with one quarter of the initial charge, and so on.
Calculate the force that charges exert on each other; Determine the direction of the electric force for different source charges; Correctly describe and apply the superposition principle for multiple source charges
The simplest atom is hydrogen, consisting of a single proton as the nucleus about which a single electron moves. The electrostatic force attracting the electron to the proton depends only on the distance between the two particles, based on Coulomb's Law: \[ F_{gravity} = G \dfrac{ m_1 m_2}{r^2} \] with \(G\) is a gravitational constant
28 Ιουλ 2024 · This electric force calculator will enable you to determine the repulsive or attractive force between two static charged particles. Continue reading to get a better understanding of Coulomb's law, the conditions of its validity, and the physical interpretation of the obtained result.
The force (F) felt by a charged particle in an electric field is calculated using: F = qE. F = Force on the charged particle (N) q = the object's charge in Coulombs (C) E = strength of the electric field (N/C)
