Задача id16556

An electron flying in a vacuum into a uniform magnetic field of strength H = 32 kA/m perpendicular to the direction of the magnetic field moves in it along a circle of radius R = 2 cm. Find the potential difference U that the electron passed through before flying into the magnetic field. Neglect the force of gravity acting on the electron. The mass of the electron is m = 9.1·10-31 kg, its charge e = 1.6·10-19 C.
