What is the electric potential 10cm from a −10nC charge?

Question 2: A charge of 10nC is placed at the center of a spherical conducting shell with an inner radius 5mm and outer radius 7mm what would be electric field intensity and potential at 3mm, 6mm and 9mm.
+78 nC charge is located at point A (10cm, 10cm ). What is the x component of electric field at point O (0,0)?
Please answer as much as possible

If a positive charge moves toward higher electric potential, what will happen to its electric potential energy? How about if it moves along an equipotential? If a negative charge moves toward higher electric potential, what will happen to its electric potential energy? How about if it moves akng an equipotential ?
