A cosmic ray proton impinges on the earth near the equator with a vertical velocity of 2.8×10^7 m/s.

A cosmic ray proton impinges on the earth near the equator with a vertical velocity of 2.8×10^7 m/s. If the horizontal component of the Earth’s magnetic field at the equator is 30 microTeslas, calculate the ratio of the magnetic force on the proton to the gravitational force on it.
