Solution: Click For PDF Version Mass of the proton,
Charge of the proton,
Velocity of the proton,
and the Earth’s magnetic field at the equator,
At the equator the Earth’s magnetic field in the north-south direction and as the proton is coming down vertically, the velocity vector of the proton and the Earth’s magnetic field vector will be orthogonal. Magnetic force on proton will be where
Therefore,
The gravitational force on the proton will be |
