A place where the vertical component of ...

A place where the vertical component of Earth's magnetic field is zero has the angle of dip equal to ......... .

A

`0^@`

B

`60^@`

C

`90^@`

D

`45^@`

Text Solution

Verified by Experts

The correct Answer is:
A
In `tan phi = (B_V)/( B_h) , B_V = 0`
`therefore tan phi = (0)/(B_h)`
`therefore tan phi = 0 therefore phi = tan^(-1) (0) therefore phi=0^@`
