Learning Goal: To understand why charged particles move in circles perpendicular to a magnetic field Correct and why the frequency is an invariant. A particle of charge q and mass m moves in a region of space where there is a uniform magnetic field B = Bok (i.e., a magnetic field of magnitude Bo in the +z direction). ( Part B Figure 1) In this problem, neglect any forces on the particle other than the magnetic force. This force will cause the path of the particle to curve. Therefore, at a later time, the direction of the force will have a component along the direction of motion remain perpendicular to the direction of motion have a component against the direction of motion first have a component along the direction of motion; then against it; then along it; etc. Subm Previous Answers Correct Part C V The fact that the magnetic field generates a force perpendicular to the instantaneous velocity of the particle has implications for the work that the field does on the particle. As a consequence, if only the magnetic field acts on the particle, its kinetic energy will _ increase over time O decrease over time remain constant oscillate Previous Answers Correct Part D Figure 1 of 1 > If the resulting trajectory of the charged particle is a circle, what is w, the angular frequency of the circular motion?
