At certain place, the horizontal component of earth's magnetic field is ( 3.0 G ) and the angle dip at that place is ( 30^ ). The magnetic field of earth at that location

Options

  1. AO.5 G
  2. B( 5.1 G )
  3. C( 3.5 G )
  4. D( 6.0 G )

Correct answer

C. ( 3.5 G )

Step-by-step solution

Given, horizontal component of Earth's magnetic field =3.0 G ; angle of dip =30^ Now, horizontal component = B (angle of dip) 3.0 G=B 30^ B= 3.0 30^ = 3.0 2 3 B=2 3 =3.464 3.5 G Therefore, magnetic field of Earth at that location =3.5 G
