**calutron**. Assuming an electronmagnet that produces a magnetic field of magnitude $B = 1\text{ T}$ and a voltage oven rated at a potential difference of $V = 2\text{ kV}$ are available, what is the radius of the path traveled by the uranium-235 being isolated? Assume the beam of vaporized uranium is ionized to a charge of $q = 1.6\times10^{-19}\text{C}.$
