21. Two wires each carrying a steady current $I$ are shown in four configurations in Column I. Some of the resulting effects are described in Column II. Match the statements in Column I with the statements in Column II and indicate your answer by darkening appropriate bubbles in the $4 \times 4$ matrix given in the ORS.

centers of the circular wires, which have same radii.\\
(D) Point P is situated at the common center of the wires.

\section*{Column II}
(p) The magnetic fields ( $B$ ) at P due to the currents in the wires are in the same direction.\\
(q) The magnetic fields ( $B$ ) at P due to the currents in the wires are in opposite directions.\\
(r) There is no magnetic field at P .\\
(s) The wires repel each other.
