We have a triangular uniformly charged plate of charge density .
We take a point just above a vertex of the triangular plate at a distance perpendicular to the plane of the triangle. Let the vertical component of electric field at that point be in
Find
Details and Assumptions:
1)
2) The triangle is equilateral. By vertical component of electric field I mean electric field perpendicular to the plane of charge.
3) The plate is non conducting.
