I need help solving these physics questions!?
Consider a particle with a charge of of 1.3C.
a) Find the electric potential at point A, located 1.5m north of the particle.
b) Find the electric potential at point B, located 2.0 m above the particle.
c) Would it require extra work to move an electron from point A to B or could the electron do work moving from point A to B?
d) How much work would be required or released moving an electron from point A to B?
(Electric potential and work are scalars.)
***NOTE: For a) I got 7.7913x10^9 V and for b) I got 5.8435x10^9 V.
I am having trouble with c) and d) since I am not quite sure how to start them. Thanks!

c) Work would be required to move a negative charge (electron) to the location of lower potential.
d) W = q(V2 - V1) = -1.602e-19C * (5.84 - 7.79)e9V = 3.12e-10 J
or if you want eV,
W = -1e * (5.84 - 7.79)e9V = 1.95e9 eV
