Resonance Frequency Of A proton

[fmdk]

Good Afternoon,

I need help on the folloewing question:

The Earth's magnetic field is relatively homogenous over large areas.

therefore how do we calculate the resonance frequency of a proton?

Could someone please direct me to formulas, variables and possible outcomes/solutions to this problem?

Thank You

fmdk
