If the angle of dip at two places are `30^(@)` and `45^(@)` respectively, then the ratio of horizontal components of earth's magnetic field at the two places will be

A

`sqrt3: sqrt2`

B

`1: sqrt2`

C

`1 : sqrt3`

D

`1: 2`

Text Solution

Verified by Experts

The correct Answer is:
A
`(B_(H_(1)))/(B_(H_(2))) = (B_(e) cos 30^(@))/(B_(e) cos 45^(@)) = (sqrt3)/(2) xx sqrt2 = (sqrt3)/(sqrt2)`
