Can the dip at a place be (a) zero (b) `90^@`?

Dip circle can be used to determine the angle of dip at a place . Dip circle consists of a magnetic needle free to rotate in a vertical plane . The end points of the needle move over a vertical circular scale . This arrangement can rotate about vertical axis . The angle rotated about vertical axis can be read from a horizontal scale . If a dip circle is further rotated about vertical axis by 60^(@) then the apparent dip at that position will be

The original value of the angle of dip at a place is 45^(@) what will be the apparent dip angle on a plane inclined at 60^(@) with the magnetic meridian ?

What is the angle of dip at a place where the horizontal component (B_(H)) and vertical component (B_(v)) of earth.s magnetic field are equal:

Explain the meaning of the statement: "Angle of dip at a certain place on earth is 60^(@) .

If the angle of dip at two places are 30^(@) and 45^(@) respectively, then the ratio of horizontal components of earth's magnetic field at the two places will be

A magnet is suspended in such a way that it oscillates in the horizontal plane. It makes 20 oscillations per minute at a place where dip angle is 30^(@) and 15 oscillations minute at a place where dip angle is 60^(@) . The ratio of total earth's magnetic field at the two places is

The angle of dip at a certain place on earth is 60^@ and the magnitude of the earth's horizontal component of the magnetic field is 0.26 G . The magnetic field at the place on earth is

Can the resultant of two vector be zero

A dip circle shows an apparent dip of 60^@ at a place where the true dip is 45^@ . If the dip circle is rotated through 90^@ , what apparent dip will it show?

The true value of angle of dip at a place is 60^(@) . The apparent angle of dip , when a magnetic needle is rotated through 30^(@) from the magnetic meridian at the same place , is
