It is no where related to magnetics. Probably u have not understood my question. A charge distribution may produce uniform electric field or an varying electric field. In case field how to find the self potential energy of the body producing varying electric field???

The heights by the great men reached and kept were not attained by a sudden flight ,but they while their companions slept were toiling upwards in the night.

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

I think I got it!!!! Suppose u is the energy density, then u = ½ E0 E2. And also according to gauss theorem, if r is the distance from the centre, then electric field at a distance r is E= 1/4piE0 (q/r2) Energy store in dr thickness is dU=1/2 E0 E2 (4pi r2 dr) we will put the value of E. dU = ½ E0 [1/4piE0 (q/r2)] ((4pi r2 dr) dU= (q2/ 16piE0 ). (2pi dr) dU= q2 dr/r2 if u integrate this U= q2/ 8piE0 [ ] [ ] dr/r2 {note from R to infinity) { R is radius} U= q2 / 8pi E0 R Phew!!! Hope dis is the ans!!!

I think bond is right .He has given the concept in general for both varying electric and magnetic field , but ashgirl has explained it clearly !
