If the ratio of magnetic fields at two points in a
\( \mathrm{P} \)
definite direction due to a long current carrying wire
W
is \( 3 / 4 \), then the ratio of the distances of these points from the wire will be:
(1) \( \frac{2}{\sqrt{3}} \)
(2) \( \frac{4}{3} \)
(3) \( \sqrt{\frac{3}{4}} \)
(4) \( \sqrt{\frac{3}{2}} \)
