## Homework Statement

hello, the problem is that i have charge [tex]q[/tex] which lies in [tex]d[/tex] distance from a plane and I need to find function [tex]\sigma[/tex] which describes density of this charge

## The Attempt at a Solution

I wrote this situation in cylindrical coordinate system where [tex]q[/tex] lies in point [tex]A=(0,0,h)[/tex] and plane lies in [tex]z=0[/tex], because of symmetry I can suppose that this function will be [tex]\sigma=\sigma(\rho)[/tex], what now?

edit: there should have been [tex]\sigma=\sigma(\rho)[/tex] I dont know why edit dont work
