Expert Solution
Introduction:

We are given 2 cases. In first case zero potential is chosen at infinity. In second case, zero potential is chosen at point P.  We find the potential at point M in both cases. Potential difference between 2 points is the work done in moving a unit positive charge from one point to another.
