The angle of dip at a place is `37^(@)` and the vertical component of the earth's magnetic field is `6xx 10^(-5)T.` The earth's magnetic field at this place is `(tan 37^@=3/4)`

Text Solution

Verified by Experts

`tan theta=V/H=3/4[:. tan 37^(@)=3/4]`
`:.V=3/4H`
`V=6xx10^(-5)T`
`H=4/3xx6xx10^(-5)T=8xx10^(-5)T`
`:.B_("total")=sqrt(V^(2)+H^(2))=sqrt((36+64))xx10^(-5)`
`=10xx10^(-5)=10^(-5)T`
