A ring of radius R is placed in the plane with its centre at origin and its axis along the x -axis and having uniformly distributed positive charge. A ring of radius r (<<R ) and coaxial with the larger ring is moving along the axis with constant velocity, then the variation of electrical flux (phi) passing through the smaller ring with position will be best represented by
