Divergence in spherical coordinates.

The use of Poisson's and Laplace's equations will be explored for a uniform sphere of charge. In spherical polar coordinates, Poisson's equation takes the form: but since there is full spherical symmetry here, the derivatives with respect to θ and φ must be zero, leaving the form. Examining first the region outside the sphere, Laplace's law ...The divergence theorem states that the surface integral of the normal component of a vector point function “F” over a closed surface “S” is equal to the volume integral of the divergence of. \ (\begin {array} {l}\vec {F}\end {array} \) taken over the volume “V” enclosed by the surface S.

These properties make the new filtering operation particularly useful to analyzing and …

This is because spherical coordinates are curvilinear coordinates, i.e, the unit vectors are not constant.. The Laplacian can be formulated very neatly in terms of the metric tensor, but since I am only a second year undergraduate I know next to nothing about tensors, so I will present the Laplacian in terms that I (and hopefully you) can understand.Viewed 10k times. 1. I've been asked to find the curl of a vector field in spherical coordinates. The question states that I need to show that this is an irrotational field.

Cylindrical and spherical coordinates were introduced in §1.6.10 and the gradient and Laplacian of a scalar field and the divergence and curl of vector fields were derived in terms of these coordinates. The calculus of higher order tensors can also be cast in terms of these coordinates. For example, from 1.6.30, the gradient of a vector in ...Solution: Solenoidal elds have zero divergence, that is, rF = 0. A computation of the divergence of F yields div F = cosx cosx= 0: Hence F is solenoidal. b. Find a vector potential for F.

Why are these additional factors necessary? I thought the metric tensor was already computed in $(r, \phi, \theta)$ coordinates. $\endgroup$ –
