The figure shows a circular loop of radius a with two long parallel wires (numbered 1 and 2) all in the plane of the paper. The distance of each wire from the centre of the loop is d. The loop and the wire are carrying the same current I.The current in the loop is in the counterclockwise direction if seen from above.
(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.
Q.4.When d ≈ a but wires are not touching the loop, it is found that the net magnetic field on the axis of the loop is zero at a height h above the loop. In that case 
  • a)
    current in wire 1 and wire 2 in the direction PQ and RS, respectively and h ≈ a
  • b)
    current in wire 1 and wire 2 in the direction PQ and SR, respectively and h ≈ a
  • c)
    current in wire 1 and wire 2 in the direction PQ and SR, respectively and h ≈ 1.2a
  • d)
