A 2.3-keV proton is moving horizontally and passes perpendicular to the Earth’s magnetic field at a location where the field magnitude is 52.0 T.

i) Determine the magnetic force on the proton?

ii) Find the ratio of this force to the gravitation force on the proton?

iii) What energy of proton would be needed to make the magnetic and gravitational forces to be equal?

iv) What direction proton would be, to keep the motion in horizontal?
