Recently I solved an question of @Jatin Yadav Force of interection Click here
In this question I calculate Force of interaction by First Calculating Electric field due to long wire and then calculate force between them ( Which is Well explained in Jatin's Solution ). I had also solved that in this way First.
In That Question If we consider Electric field due disc element in hemisphere and then Find The Force of interaction then How We can calculate This ?
Consider an disc element on Hemisphere and small line element on wire as shown in figure .
Sorry For poor Diagram But please Feel it
Now I use standard result of electric field due to an uniformly charged disc
But From Here I get stuck
How can I find this integral ..??
Also When I use wolfram alpha then it says this this Integral not converges.!!
So please Tell Me where I'am wrong. ??
