# NEET Physics Magnetism and Matter Questions Solved

A magnet oscillating in a horizontal plane has a time period of 2 second at a place where the angle of dip is 30o and 3 seconds at another place where the angle of dip is 60o. The ratio of resultant magnetic fields at the two places is

(a) $\frac{4\sqrt{3}}{7}$                         (b) $\frac{4}{9\sqrt{3}}$

(c) $\frac{9}{4\sqrt{3}}$                         (d) $\frac{9}{\sqrt{3}}$
