Two coaxial circular loops 1 and 2, which form same semi vertical angle \( \theta \) at point \( O \). Same charges are uniformly distributed along the circumference of both the loops. The loops are rotating with same angular velocity in same direction about their axis through centre of mass and perpendicular to their plane. If \( B_{1} \) and \( B_{2} \) are magnetic field due to the loops 1 and 2 respectively, then
(1) \( \frac{B_{1}}{B_{2}}=2 \)
(2) \( \frac{\mathrm{B}_{1}}{\mathrm{~B}_{2}}=\frac{1}{2} \)
(3) \( \frac{\mathrm{B}_{1}}{\mathrm{~B}_{2}}=8 \)
(4) \( \frac{B_{1}}{B_{2}}=4 \)
\( \mathrm{P} \)
