I need help with a,b, and c. My professor won't help me and I am helping problem will this problem. Can you label which one is A, B and C, thank you so much

Problem 1: Derive Equation 23.11 of the textbook for the field Edipole in
the plane that bisects an electric dipole,
Ēdipole

FIG. 1: The scheme for Problem 1
a) In Fig. 1, draw the vectors that represent the electric fields Ē, and
E-generated in point P by the charges q and -q, respectively. Draw
a vector that represents the dipole moment of the system, p. Which
(horizontal or vertical) components of the fields Ē, and E_ cancel each other and which components add
up? Is the direction of the total field E in point P the same as the direction of p or opposite to it?
b) Compute the absolute values of those components of E, and E_ that do not cancel each other and
use them to find the magnitude of the total electric field in point P, |E|. You can use the angle shown in
the diagram, but make sure to express the final answer in terms of r, s, and q.
c) Find the limit of El for r»s. What is the magnitude of the dipole moment p? Taking into account
the directions of vectors E and p, can you reproduce Equation 23.11 of the textbook?
