    How Does a Positron's Kinetic Energy Change with Magnetic Field Strength?

    Homework Statement A positron moves in a circular path of radius R due to a uniform magnetic field of strength B applied perpendicular to the plane of the circle. If B is varied, which of the following best represents a graph of the kinetic energy of the positron as a function of B so that the...
