A) In the XY plane there is an electrically charged ring, with an electrical charge of 5C and a radius R. On the other hand, there is a point electrical charge -1C in (0, 0, 2). Calculate the electrical potential in points of the shape (0, 0, z) (where z is different from 0).
From this potential, calculate the electric field E⃗ (0, 0, z).

B) A disc of radius R uniformly charged electrically, with total electrical charge 5C, located in the XY plane. Calculate the electrical potential for points on the symmetry axis of the disc. Calculate the electric field from the potential.
