# electric field at surface of a conducting sphere...

recently, i tried to find electric field at surface of a charged dielectric and a conducting sphere without using guass law, rather using standard method of integration.... for dielectric sphere i got it right but for conducting one, dividing into thin rings and analysing the fields due to them i got the field less by a factor of 2 . please try to find field like this, and if you get correct, tell where i was missing. see the attachment... i forgot dtheta so i had to edit.... thanks in advance.....

Well, I didn't know latex 10 months ago :P

Just ignore it. I found what was wrong.

Could you tell whats wrong??

Actually, I didn't add the electric field due to small charge just on the given point, adding which($$\dfrac{\sigma}{2 \epsilon_{0}}$$), we get correct answer.
