Can you explain more detailed and clearly each part
Near an electric point charge in a vacuum, all points on the dashed line below have the same electric potential +9V with respect to a very distant reference point. For the exact description of the situation, the sketched Cartesian coordinate system with the scale division of 1m is used, in which, among other things, the points A and B with the coordinates xA = -1m, yA = 2m and xB = 1m, yB = 2m are of interest. Note ε0 = 8.85 x 10^-12 As/Vm
a) Briefly explain why the field-generating point charge q is not at the origin of the sketch below!
b) Determine the magnitude of the charge |q|. Is q a positive charge or a negative charge? Explain briefly!
c) What is the magnitude of the electric field strength |E| and |E| at the points A and B? Enter the directions of the electric field strength vectors E and E at these points in the sketch below.
d) Draw in the following sketch the equipotential line whose points have the potential = 2+18V with respect to a very distant reference point.
