This law is often used alongside the method of images when dealing with plate barriers.
This law is often used alongside the method of images when dealing with plate barriers. One application of this law can be used to show that a person inside a planet is only pulled by the gravity of the ground beneath him and not above. A modification of one version of this law sets one side of it equal to mu nought times row m instead of 0 and allows for magnetic monopoles. The differential and integral forms of this law are equal according the divergence theorem, which was also discovered by this law's namesake. One version of this law states that the divergence of the electric field is equal to the charge density over the permittivity of free space; or that the electric flux through a closed surface is equal to the enclosed charge over the permittivity of free space. For 10 points, give this law, whose electrical and magnetic versions form half of Maxwell's equations for electromagnetism.
