I've posted one question here Please guide me. This question is related to electrical self energy from electrostatic but it was put on hold because it was a homework question. So I edited it following the same rules for editing questions as suggested but it is still on hold! Please help me.
First, as of now, zero people have so far reviewed your edited question. It's not even been an hour. Patience.
Second, and more importantly: even in its present form (v3), your question is much more like "solve this problem for me" than like the type of conceptual homework-like questions we accept here. It's not clear whether you are having a mathematical question about relating the distance from a source charge with the radius of a sphere, or whether you are confused about the concept of electrical self-energy, or whether you are confused about the difference between a volume charge and a surface charge. Without knowing what your conceptual stumbling block is, the odds aren't good that an answerer would be able to guide you to a solution. In that case, it'd be appropriate for the question to remain closed.
Try re-reading the homework guidelines and reading some other questions on electrostatic self-energy to see the kinds of changes that would make your question answerable here. Good luck!
