What is the potential difference between points A and B and the potential difference between points B and C?

2. A) In Figure 1 we see a point charge of + 2.00n C. Two circles are drawn around the point charge. The charge is located in the center of these dotted circles. The innermost has a radius equal to 1.00cm, and the outer has a radius equal to 2.00cm. On the innermost circle there are drawn in points A and B. On the outermost circle there is drawn in point C.

1.Find the electrical potential at points A, B and C

2. Find the electrical potential energy of an electron if the electron is placed in points A, B and C, respectively.
3. What is the potential difference between points A and B and the potential difference between points B and C?
4. Sketch electric field lines and equipotential surfaces around the charge
