The real angle of dip, if a magnet is suspended at an angle of `30^(@)` to the magnetic meridian and the dip needle makes an angle of `45^(@)` with horizontal, is:

A

`tan^(-1)(sqrt3/2)`

B

`tan^(-1)(sqrt3)`

C

`tan^(-1)(sqrt(3/2))`

D

`tan^(-1)(2/sqrt3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`tandelta.=tandelta/cosalpha`
`delta` = true dip, `delta.` = dip with the field
`alpha` = angle made by the meridian
