The vertical component of earth's magnetic field at a place is `sqrt3` times the horizontal component the value of angle of dip at this place is

A

`60^(@)`

B

`30^(@)`

C

`45^(@)`

D

`0^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
As, vertical component of Earth's magnetic field is
`" " B_(v)=sqrtB_(H)`
Angle of dip at any place is given by,
`" " tan delta=(B_(v))/(B_(H))=(sqrt3B_(H))/(B_(H))=sqrt3`
`" " delta=tan^(-1)(sqrt3)=60^(@)`
