An electron is accelerated from rest through a voltage of $1,101V$ enters a region of constant magnetic field. If the electron follows a circular path with a radius of $22\mathrm{.}1$ cm $,$ what is the magnitude of the magnetic field?

Report your answer in units of millitesla, ${10}^{-3}T.$ For example, if your calculations produce a value of $1\mathrm{.}23{10}^{-3}T,$ first convert units to get $1\mathrm{.}23$ mT $,$ then enter your answer as $1\mathrm{.}23.$
