- Proton 1 moves with a speed v from theeast coast to the west coast in the continental United States; proton 2 moves with the same speed from the southern United Statestoward Canada. (a) Is the magnitude of the magnetic force experienced by proton 2 greater than, less than, or equal to the forceexperienced by proton 1? (b) Choose the best explanation fromamong the following:I. The protons experience the same force because the magneticfield is the same and their speeds are the same.II. Proton 1 experiences the greater force because it moves atright angles to the magnetic field.III. Proton 2 experiences the greater force because it moves in thesame direction as the magnetic field.A helium plasma with equilibrium electron density noe and equilibrium positive ion density noi.
