The angle of dip at a certain place on earth is `60^(@)` and the magnitude of earth's horizontal component of magnetic field is 0.26 G. The inagnetic field at the place on earth is

A

0.13G

B

0.26G

C

0.52G

D

0.65G

Text Solution

Verified by Experts

The correct Answer is:
C
Horizontal component of the earth,s magnetic field,
`H_(E)=0.26G`
Angle of dip , `delta=60^(@)`
`cosdelta=(H_(E))/(B_(E))`
where `B_(E)` is the magnetic field of the eatth
`:.B_(E)=(H_(E))/(cosdelta)=(0.26G)/(cos60^(@))=(0.26G)/((1"/"2))=0.52G`
