The horizontal component of earth's magnetic field at a place is `3.6 xx 10^(-5)` T. if the angle of dip at this place is `60^(@)`, the vertical components of earth's field at this place is

A

`1.2 xx 10^(-5)` T

B

`2.4 xx 10^(-5)` T

C

`4 xx 10^(-5)` T

D

`6.2 xx 10^(-5)` T

Text Solution

Verified by Experts

The correct Answer is:
A, B
`B_(v) = B_(H) tan delta = 3.6 xx 10^(-5) xx tan 60^(@)`
`B_(v) = 6.2 xx 10^(-5) ` T
