Two normal uniform magnetic field contain a magnetic needle making an angle `60^(@)` with F. Then the ratio of `F/H` is

A

`1:2`

B

`2:1`

C

`sqrt(3):1`

D

`1:sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
D

From figure at euilibrium
`tan 60^(@) =H/F`
`implies sqrt(3)=H/F implies F/H=1/sqrt(3)`
