oh meine book ka ques kardia
:aah:
Ig 2 element maan kar force to calculate kia ja sakta hai theta ko variable bana kar
Jese dipole moment k calculation me karte hai
The integral u see in red acc somehow goes to inf
I think its maybe cuz ive taken limits frkm 0 to 2pi and the force on a element due to itsekf is not defined thats why maybe
Now i understood what u did actually
Is there any other way then
ig u can integrate from x to 2pi-x by considering an very small arc subtending a small angle x and we cn then find electric field on this arc due to rest of ring and balance tension forces to that force due to field, that way we can get a valid result and also u can expand Ln(cot(x/4)) using taylor and stuff and yea the limits still tends to infinity ig when x tends to 0 in this expression
