If a proton is moving perpendicular to a uniform magnetic field, it will experience a magnetic force that will pull the proton out of its straight- line path and cause it to travel in a circle of radius r. Find the magnitude of the magnetic force for a proton moving at 3x10 m/s perpendicular to a magnetic field of 1.5 T.​

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )
