The correct value of dip angle at a place is 45o. If the dip angle is rotated 45oout of the meridian, the tangent of the apparent dip is
1
1/√2
√2
1/2
The vertical component of the earth’s magnetic field is zero at a place where the angle of dip is
0o
45o
60o
90o
The needle of a dip circle when placed at a geomagnetic pole stays along
South - North direction only
East - West direction only
Vertical direction
None of the above
At a certain place the horizontal component of earth’s magnetic field is a √3 time the vertical component, the angle of dip is
15o
30o
The angle between the magnetic meridian and geo meridian is known as
Magnetic dip
Magnetic declination
Magnetic latitude
Magnetic longitude
At a place the horizontal component Bo and vertical component Vo of the earth’s magnetic field are equal in magnitude. The total intensity at a place is
Bo
Bo2
2Bo
√2 Bo
Choose the right one from the following. A deflection magnetometer can be used for measuring
Declination
Dip
Horizontal component
All the above
If the earth’s horizontal and vertical components are equal at a certain point, the angle of dip is,
Zero
