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 wires are carrying the
same current . The current in the loop is in the counterclockwise direction if seen from above
When $\mathrm{d} \approx$ a but wires are not touching the loop, it is found that the net magnetic filed on the axis of the loop is zero at a height $h$ above the loop. In that case
Select the correct option:
A
current in wire 1 and wire 2 is the direction $P Q$ and $R S$, respectively and $h \approx a$
B
current in wire 1 and wire 2 is the direction $P Q$ and $S R$, respectively and $h \approx a$
C
current in wire 1 and wire 2 is the direction PQ and SR , respectively and $\mathrm{h} \approx 1.2$ a
D
current in wire 1 and wire 2 is the direction PQ and RS , resepectively and $\mathrm{h} \approx 1.2 \mathrm{a}$
