Sketch the vector function and compute its divergence. Divergence to the above vector point function can be expressed as follows. Find scalar function so that vector field has no divergence. Note that gauss theorem is typically derived for functions defined on the whole volume otherwise how can you integrate it over the volume so there is no a priori contradiction between gauss theorem in that the divergence is zero yet a surface integral around r0 equals 4pi.
Ask question asked 3 years 1 month ago. B do the same for v 2 1r2r. I introduce the dirac delta function by showing the necessity of it.
Im following the text introduction to electrodynamics by griffiths and i came across the following in an in text problem. Here are the partial derivatives of function with respect to respectively. Sketch the vector function v fracboldsymbolhatmathbfrr2 and compute its divergencethe answer may surprise you.
Can you explain it. If the answer surprises you look back at prob. Calculate the divergence of a vector field without the definition.
This vector field seems to have a divergence of zero but the flux is clearly 4 pi. A check the divergence theorem for the function v1 r2r using as your volume the sphere of radius r centered at the originb do the same for v2 1r2r. That is the purpose of the first two sections of this chapter.
Consider a vector point function. In this section we are going to introduce the concepts of the curl and the divergence of a vector. Well the answer did surprise me for the sketch of the function is indeed indicating a diverging field like field.
Stack exchange network stack exchange network consists of 175 qa communities including stack overflow the largest most trusted online community for developers to learn share their knowledge and build their careers. Here are the components of function respectively. Sketch the vector function and determine the divergence.
Lets start with the curl. Given the vector field fpiqjrk the curl is defined to be. Sketch the vector functionv rr2an compute its divergence this problem has been solved.
Sketch the vector function v r r 2 an compute its divergence. Divergence applies to scalar function. If the answer surprises you look back at prob.
The mathematical form of divergence is as follows.
