In this problem, we are dealing with electric potential.
The potential at a point is some of the potentials due to all charges at that point.
Four charges, each of magnitude +Q are placed at the corners of a square of side a. Obtain an expression for the electric potential at the centre of the square and at the mid point of one side. What is the direction of the electric field at the centre of the square and at the mid-point of the side.
