Please see the attached file for the full problems:
1) A 2µC point charge is located at A(4,3,5) in free space.
i) Find Eρ, Eφ, and Ez at P(8,12,2).
2) A charge Qo located at the origin in free space produces a field for which Ez =
1kV/m at point P(-2,1,-1).
i) Find Qo
ii ) Find E at M(1,6,5) in rectangular, cylindrical , and spherical coordinates.
This solution solves electromagnetic problems, including calculations.
