Consider a, practically,infinite metallic conductor in which inside there is a spherical cavity with radial R. At the paries there is a surface allocation of electric brunt with a surface density: σ(θ)=σοcosθ .
θ: polar angle at teh system of spherical coordinates with the center at the center of cavity.
Find the electric field at each point of the cavity.

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution

Inside the conductor, the electric field it's zero.
I think inside the cavity the field is zero
And at the surface of the cavity how can I work?
