Singly ionized (one electron removed) atoms are accelerated and then passed through a velocity selector consisting of perpendicular electric and magnetic fields. The electric field is 157 V/m and the magnetic field is 3.12×10−2 T . The ions next enter a uniform magnetic field of magnitude 1.78×10−2 T that is oriented perpendicular to their velocity.

Part A How fast are the ions moving when they emerge from the velocity selector?

Part B If the radius of the path of the ions in the second magnetic field is 17.1 cm , what is their mass?

    A mixed gas consisting of CO, CO2, and H2O molecules is first ionized so each molecule is singly ionized. Each molecule is then accelerated through a potential difference of 25.6 kV. Once accelerated, the molecular beam enters a magnetic field of 0.525 T that is perpendicular to the beam. Determine the velocity of each molecule before entering the magnetic field. Determine the radius of curvature for each molecule as it travels in the magnetic field. Sketch the situation showing where...

  • Velocity Selector-multiple choice

    The Velocity SelectorIn experiments where all the charged particles in a beam are required to have the same velocity (for example, when entering a mass spectrometer), scientists use a velocity selector. A velocity selector has a region of uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the motion of the charged particles. Both the electric and magnetic fields exert a force on the charged particles. If a particle has precisely the right velocity, the...
