At place, the magnitudes of the horizontal component and total intensity of the magnetic field of the earth are 0.3 and 0.6 Oersted respectively. The value of the angle of dip at this place will be

A

`60^(@)`

B

`45^(@)`

C

`30^(@)`

D

`0^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
`B_(H)=0.3` Oersted, `I=0.6` Oversted
We have `B_(H)=I cos varphiimpliescosvarphi=B_(H)/I=0.3/0.6 =1/2`
`:. varphi=60^(@)`
