Divergence theorem in emft

WebThe uniqueness theorem for Poisson's equation states that, for a large class of boundary conditions, the equation may have many solutions, but the gradient of every solution is the same.In the case of electrostatics, this means that there is a unique electric field derived from a potential function satisfying Poisson's equation under the boundary conditions. WebThe divergence of the given vector field is Thus, by divergence theorem, the flux is We can show this result by direct integration. The unit normal on the surface of the sphere is …
