Answer:
Magnetic force, 
Explanation:
It is given that,
Magnetic field, B = 2 T
Velocity of the proton, v = 300 m/s
Charge on the proton, 
The magnetic field is oriented perpendicular to the proton’s velocity. The magnetic force on the charged particle is given by :

The magnetic field is oriented perpendicular to the proton’s velocity, 


So, the magnitude of the force that the proton experiences while it moves through the magnetic field is
. Hence, this is the required solution.
