Inside the conductor there is a cylindrical hole of radius ‘a’ whose axis is parallel to the axis of the conductor and at a distance ‘b’ from it, as shown in the diagram .The conductor with hole carries current i. Let the z-axis be the axis of conductor and the axis of the hole at x = b, Match the following column.
