A charged particle, after entering a constant magnetic field B, starts moving freely along a circular path in the magnetic field applied perpendicular to the particle’s velocity (v). What do you conclude about the particle’s kinetic energy (KE)? Group of answer choices KE remains unaltered as v and FB are perpendicular to each other KE increases under the constant magnetic force FB. KE decreases when magnetic force (FB) is perpendicular to the motion (v). KE and magnetic force FB are not correlated.
