The net electromagnetic force exerted on a charged particle moving through a region containing both an electric field ($\vec{E}$) and a magnetic field ($\vec{B}$) is formally called the:

A particle with charge 2 Coulombs moves at 10 m/s perpendicularly through a uniform magnetic field of 3 Tesla. The magnetic force experienced is:

A proton moving parallel to a uniform magnetic field experiences a magnetic force of:
