A magnet is suspended so that it may oscillate in the horizontal plane .It performs oscillations per minute at a placewhere the angle of dip is 30 0 and 15 oscillations per minute, where the angle of dip is 60 0 . The ratio of earth’s magnetic field at these two places is 1) 16/9 2)4/3 3)8/3 4)16/9

Given v1=2060=13sec−1 and v2=1560=14sec−1
Now v=12πMBHI−−−−−−√=12πMBcosφI−−−−−−−−√(∵BH=Bcosφ)
∴v1v2=B1cosφ1B2cosφ2−−−−−−−−√⇒B1B2=(v1v2)2(cosφ2cosφ1)2
B1B2=(1/31/4)2cos60∘cos30∘=169×1/23–√/2=1693–√
