Question:
Repeat Problem 3.8, but use ∇ ·D = ρν and take an appropriate volume integral.
In Problem
Use Gauss’s law in integral form to show that an inverse distance field in spherical coordinates, D = Aar /r , where A is a constant, requires every spherical shell of 1 m thickness to contain 4πA coulombs of charge. Does this indicate a continuous charge distribution? If so, find the charge density variation with r.

I have always been passionate about teaching because of the phenomenal impact it can have on the achievements and accomplishments of a student(s). I also helped college students with various subjects such as Biochemistry, Human Physiology, Animal Kingdom, Plant Kingdom, Cell Biology, Genetics etc.
I have qualified national level eligibility test for teaching as well research. I have done my doctoral studies from Defense Research and Development Organization and have been working as Scientist at Indian Council of Medical Research. My long experience in the field of academics and research will reflect in clarity and simplicity in my teaching. I can teach students very lucidly with diagrams, flow charts and shortcuts for excellent understanding of the concepts.
