An electron starts from rest, is accelerated through a potential difference V, and then enters normally into a uniform magnetic field B. It follows a circular path of radius r and has de Broglie wavelength λ. In a second experiment, the electron is accelerated through 9V and then enters a magnetic field 3B. Which pair correctly gives the new radius and wavelength?
