Electrostatics equations

Electrostatics is the theory of the electric field subject

The equations describe how the electric field can create a magnetic field and vice versa. Maxwell First Equation. Maxwell’s first equation is based on the Gauss law of electrostatic, which states that “when a closed surface integral of electric flux density is always equal to charge enclosed over that surface”For these cases, Equation 11.5.1 can be written as: F(r) = − dPE(r) dr. where F(r) is the magnitude of a force which points along the radial component ˆr. To solve for potential energy in terms of force, you can rewrite Equation 11.5.3 in terms of an integral of force over distance.Physical meaning of the separation constants in Laplace's Equation for Electrostatics. 4.
