At certain place, the horizontal component of earth.s magnetic field is 3.0 G and the angle dip at that place is `30^(@)`. The magnetic field of earth at that location

A

`4.5G`

B

`5.1G`

C

`3.5G`

D

`6.0G`

Text Solution

Verified by Experts

The correct Answer is:
C
`B_(H)=3G`
`Bcos30^(@)=3`
`B=3sec30^(@)`
`=3xx(2)/(sqrt(3))=(6)/(1.732)impliesB=3.5G`
