Potential
I tried to do this by taking infinite wires from one edge of the disc to the other edge but couldn't do it

Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.just remember this one as a case V=sigmaR/pie*epsilon
@Chai Enjoyer take elemental ring instead of wire
If you wanna solve it you need to integrate. Take a small ring element with area dA and integrate it from 0 to pi*R^2
0 to R i think
Oh yes my bad, 0 to R. I forgot that dA will get simplified to Radius as variable
Nvm jaldibaji me kabhi kabhi ho jata 👍
But for that you need to know the potential by a ring on the side
@Chai Enjoyer yeah you are right we have to that also so it will be multi step.. there is direct step solution on internet but its too complicated
My teacher did it with double integration but i didn't understand shit
Hmm isliye mene bhi yaad kar rakha hai result iska.. wait till morning i will try to solve in multi step tab tak thread chalu rakhna. good night
Good night!
@Chai Enjoyer btw you gave JEE?
No I'm 25tard
its a thin disc, the thickness is neglected
Bro if you're considering rings emerging from the center than for finding their potential for integration you have to know potential on plane of ring, how you gonna do that?
This is how it’s done
The integral sine thing at last comes out as equal to one
@Chai Enjoyer did this help
OMG thanks
I'll close the post later since progamology said so
Ok
@Chai Enjoyer i can't find simpler method than double integration... if you having problem in the double integration solutions then watch this advance illustration vid of ashish arora sir https://youtu.be/mY9e7Sbf70g?si=HKyl6rtRCCi_bXkN
Very nice explanation bro
Thanks
