An electron accelerated by a potential difference \[F=\text{ }1.0\text{ }kV\] moves in a uniform magnetic field at an angle \[\alpha =30{}^\circ \] to the vector \[\overrightarrow{B}\] whose modulus is \[B\text{ }=\text{ }29\text{ }mT.\] Find the pitch (in cm) of the helical trajectory of the electron.
