Homework Equations
While solving this problem at r >>a ,the corresponding potential due to the dipole is kpcosθ/r2(potential due a dipole) where k is the electrostatic constt. ...(1)
If σ(θ) is the surface charge density induced due to external electric field.
then the dipoel moment of the configuration is 2π∫σ(θ)a3sinθ cosθ dθ from 0 to π...(2)
Now comparing (1) with the right most term of potential given in question the dipole moment is p=4πε0a3
And comparing this with (2)
4ε0=∫σ(θ)sin2θdθ from 0 to π.
Now the charge density at 30° is to be calculated .
will anyone please help me in sort out this.as I got stuck here.
