σ is the charge per unit lenght.
o is the actual centre of part of the spherical shell.
to find the value of electric field at pt. b.
this is the way how i proceed.
i took a small part of shell of length dx.
then took variable distt from b in form of x & θ.
i integrate but could not relate between x & θ.& cant simplify in one variable.
please help me out..
