Question

Hi there, I am looking for help on part d) of this question. I figured a), b), and c) but solutions to those would be nice as well so I could check my answer.

Thank you

2. The electric fields for two different combinations of point charges are shown in diagrams (A) and (B) below. The charges are separated by 1.20 m and right hand point change has magnitude 2.50 nC on both diagrams. (A) (B) a) Find the charges for both diagrams. b) Sketch the equipotential contour for V=1 on diagram (A). c) For diagram (B) find the point, on the horizontal line between the two point charges, where the electric potential is zero. d) Calculate the work needed to add a point charge of 2.00 nC at a point 0.500 m above the right hand point charge in diagram (B).
