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

`sqrt(3):sqrt(2)`

B

`1:sqrt(2)`

C

`1:sqrt(3)`

D

`1:2`

Text Solution

Verified by Experts

The correct Answer is:
A
`As, (H_(1))/(H_(2))=(Bcostheta_(1))/(B cos theta_(2))=(costheta_(1))/(cos theta_(2))=(cos30^(@))/(cos45^(@))=(sqrt3)/(2)xxsqrt2=(sqrt3)/(sqrt2)`
