If a magnet is suspended an angle 30^(@)...

If a magnet is suspended an angle `30^(@)` to the magnetic field at any point on eath. Near the north pole.

A

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

B

`tan^(-1)(sqrt3)`

C

`(tan^(-1))(3)/(sqrt2)`

D

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

Text Solution

Verified by Experts

As, tan `delta'=(V)/(H)and tan delta_(1)=(V)/(Hcos(90^(@)-theta))`
`(tan delta)/(cos(90^(@)-theta))=tan delta cosec theta`
