At a certain place, the angle of dip is ...

At a certain place, the angle of dip is `30^(@)` and the horizontal component of earth's magnetic field is `50muT`. The total magnetic field (in `muT`) of the earth at this place, is

A

`(H)/(2)`

B

`(2H)/(sqrt3)`

C

`H sqrt2`

D

`H sqrt3`

Text Solution

Verified by Experts

The correct Answer is:
B
`B_(H)= B_(e) cos delta`
`rArr B_(e)= (H)/(sqrt3//2) = (2H)/(sqrt3)`
