Figure 1 shows the force on Q1 due to Q2. A numerical example will help to illustrate this force.Electromagnetism (Essentials) - Class 12th 14 units · 93 skills. Unit 1 Welcome to Electromagnetism essentials. Unit 2 How a microwave oven works? Unit 3 Maxwell's first equation - an alternative to Coulomb's law. Unit 4 The sun shouldn't be alive, here's why!The electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work energy needed per unit of electric charge to move this charge from a reference point to the specific point in an electric field. More precisely, it is the energy per unit charge for a test charge that ...Divergence of a field and its interpretation. The divergence of an electric field due to a point charge (according to Coulomb's law) is zero. In literature the divergence of a field indicates presence/absence of a sink/source for the field. However, clearly a charge is there. So there was no escape route.

$\begingroup$ So wrt Maxwell's electrostatic equations in differential form, the divergence of the electric field is proportional to the charge creating the field or in integral form the charge "enclosed" by a surface. $\endgroup$ – …In words: Gauss's law states that the net electric flux through any hypothetical closed surface is equal to 1/ε0 times the net electric charge within that closed surface. ΦE = Q/ε0. Electric flux depends on the strength of electric field, E, on the surface area, and on the relative orientation of the field and surface.Frequently used equations in physics.

But later, as we shall discuss, these two elds are found to be based on the same set equations known as Maxwell's equations. Maxwell's equations uni ed these two elds,

t. e. In electromagnetism, charge density is the amount of electric charge per unit length, surface area, or volume. Volume charge density (symbolized by the Greek letter ρ) is the quantity of charge per unit volume, measured in the SI system in coulombs per cubic meter (C⋅m −3 ), at any point in a volume.
