The horizontal component of the earth's ...

The horizontal component of the earth's magnetic field is 0.22 Gauss and total magnetic field is 0.4 Gauss. The angle of dip. Is

A

`tan^(-1)(1)`

B

`tan^(-1)(oo)`

C

`tan^(-1)(1.518)`

D

`tan^(-1)(pi)`

Text Solution

Verified by Experts

The correct Answer is:
C

By using `B_(H)=B cos varphi`
`implies cos varphi=B_(H)/B=0.22/0.4impliestan varphi=sqrt((0.4)^(2)-(0.22)^(2))/0.22`
`impliesvarphi=tan^(-1)(1.518)`
