A metallic rod \( P Q \) is hinged at point \( P \) and it can rotate about point \( P \) in vertical plane as shown in the figure. If mass of rod is \( m \) and length \( l \), then the current in \( P Q \), such that it remains in equilibrium as shown. (Separation between \( P \) and current carrying conductor \( A B \) is very small)
(a) \( \frac{2 m g \pi}{\mu_{0} i_{1}} \)
(b) \( \frac{m g \pi}{2 \mu_{0} i_{1}} \)
(c) \( \frac{m g \pi}{4 \mu_{0} i_{1}} \)
(d) \( \frac{m g \pi}{\mu_{0} i_{1}} \)
