For the same accelerating potential difference, what magnetic field should be used to send beryllium-10 ions (m = 1.663 10-26 kg) to the same location in the detector? Both types of ions are singly ionized (q = +e) A proton with a speed of 3.63 106 m/s is shot into a region between two plates that are separated by a distance of 0.24 m.

Beryllium has another special property: unlike most metals, X-rays can shine straight through it. This transparency to X-rays is due to the low number of electrons in its atoms: as element number 4 in the periodic table, it has just four electrons in each of its atoms (along with four protons and usually five neutrons within the nucleus).
