The true value of angle of dip at a place is 60^(@)`, the apparent dip in a inclined at an angle of `30^(@)` with magnetic meridian is

A

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

B

`tan^(-1). (2)`

C

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

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`tan delta =(tan delta)/(cos beta) , delta to ` apparent angle of dip
`rArr tan delta = (tan 60^(@))/(cos 30^(@)) = 2 rArr delta = tan^(-1) (2)` .
