A magnetic needle is free to rotate in a vertical plance which makes an angle of `60^@` with the magnetic meridian. If the needle stays in a direction making an angle of `tan^(-1) (2sqrt(3))` with the horizontal, what would be the dip at that place?

A magnetic needle is free to rotate in a vertical plane which makes an angle of 60^@ with the magnetic meridian. If the needle stays in a direction making an angle of tan^-1(2//sqrt3) with the horizontal, what would be the true dip at that place?

A magnetic needle free to rotate in a fixed vertical plane stays in a direction making an angle of 60^@ with the horizontal. If the dip at that plane is 37^@ , find the angle of the fixed vertical plane with the meridian.

The real angle of dip, if a magnet is suspended at an angle of 30^(@) to the magnetic meridian and the dip needle makes an angle of 45^(@) with horizontal, is:

If a magnet is suspended at an angle 30^(@) to the magnetic meridian and in this plane the dip needle makes an angle of 60^(@) with the horizontal. The true value of dip is:

A magnetic needle free to rotate about the vertical direction (compass ) point 3.5 west of the geographic north . Another magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 18^(@) with the horizontal . The magnitude of the horizontal component of the earth ' magnetic field at the place is known to be 0.40 G . what is the direction and magnitude of the earth's magnetic field at the place ?

A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 22^(@) with the horizontal . The horizontal componemt of the earth's magnetic field at the place is know to be 0.35 G . Determine the magnitude of the earth's magnetic field at the place .

A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 22^@ with the horizontal. The horizontal component of the earths magnetic field at the place is known to be 0*35G . Determine the strength of the earths magnetic field at the place.
