- Homework Statement
- An infinitely long hollow (non conducting) circular cylinder of radius R fixed at potential V =V•sin(phi) .

- Relevant Equations
- Using cylinder coordinates with z axis as a symmetric axis , argue V is independent of Z and V(r, -phi)= -V(r, phi)

b) Find electrostatic potential inside and outside of the cylinder

I solved laplacian equation. and got the solution of V(r, phi) = a. +b.lnr + (summation) an r^n sin(n phi +alpha n ) + (summation) bn r ^-n sin( n phi +beta n)
