The ratio of magnetic moments of two short magnets which give deflection in "tan"B position when placed at 12 cm and 18 cm from centre of a deflection magnetometer is

The ratio of magnetic field due to a given short bar magnet in tan A and tan B position for the same distance is

The arms of a deflection magnetometer in the tan B posittion are placed

Two short magnets having magnetic moments in the ratio 8:1 , when placed on opposite sides of a deflection magnetometer produce no deflection. If distance of stronger magnet from the centre of deflection magnetometer is 6cm , what is the distance of weaker magnet from the centre?

Two short magnet having magnetic moment in the ratio 27:8 , when placed on the opposite sides of a deflection magnetometer, produce no deflection. If the distance of the weaker magnet is 0.12m from the centre of deflection magnetometer, the distance of the stronger magnet from the centre is

Two short magnet having magnetic moment in the ratio 27:8 , when placed on the opposite sides of a deflection magnetometer, produce no deflection. If the distance of the weaker magnet is 0.12m from the centre of deflection magnetometer, the distance of the stronger magnet from the centre is

A short magnet produces a deflection of 37^@ in a deflection magnetometer in Tan-A position when placed at a separation of 10cm from the needle. Find the ration of the magnetic moment of the magnet to the earth's horizontal magentic field.
