The angle of dip at a certain place is `30^(@)`. If the horizontal component of the earth's magnetic field is H, the intensity of the total magnetic field is

A

`H/2`

B

`(2H)/sqrt(3)`

C

`Hsqrt(2)`

D

`Hsqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`B_(H)=B cos varphiimpliesB=B_(H)/(cos varphi)impliesB=B_(H)/(cos 30^(@))=(2B_(H))/sqrt(3)`
