Two intersecting conducting planes electric field

Two conducting planes intersect at an angle β = 270°. The planes are assumed to be held at potential V. Find the electric field distribution near the corner.

Problem Type:
Plane problem of electrostatics.

Geometry:
Two conducting planes intersect at an angle 270

Given:
Relative permittivity of vacuum ε = 1;
Voltage V = 100 V.

Solution:
Open space problem is converted to the closed region problem using the "zero potential" boundary far away from the studying object.
