The electric field in a region surrounding the origin is uniform and along the x-axis. A small circle is drawn with the centre at the origin cutting the axes at points B, C, and D having co-ordinates (a, 0), (0, a), (– a, 0), (0, – a); respectively as shown in figure.Potential will be maximum at the point?
