In a certain place, the versted component of earth's magnetic field is 0.5 oersted and dip angle is ` 60^(@)` . The earth's magnetic field at that place is

A

1 orested

B

` sqrt(3)/2` orested

C

2 oerested

D

` 1/(sprt(3))` oersted

Text Solution

Verified by Experts

The correct Answer is:
D
Here,
Vertical component of earth.s magnetic field , ` V_(E)=0.5 ` oersted Angle of dip, ` delta= 60^(@)`
Earth magnetic field, ` B_(E) = ?`
` "As" sin delta = (V_(E))/(B_(E)) therefore B_(E) = (V_(E))/( sin delta) = (0.5)/( sin 60^(@)) = (0.5)/((sqrt3/2)) = 1/sqrt3` oersted
