calculate the magnitude of the magnetic force acting on the proton? if it moves with a speed of $1\mathrm{.}0$x $105$ m$/$s through the earths magnetic field, which has a value of $55$mt at a particular location. when the proton moves westward the magnetic force acting on it is directed straight upward A$)$ calculate the gravitational force on the proton, and b$)$ compute the electric force ofif there were an electric field with a magnitude equal to E$=1\mathrm{.}50$x$10^2$ N$/$C at the location, a common value at earths surface. Note that the mass of the proton is $1\mathrm{.}67$x$10^-27$ kg
