Question
Captain jack Harkness needs to enable a substance that he finds on planet Ood, using a mass Spectrometer. In the second part of the mass spectrometer shown above, ions with mass m, charge q and Magnetic field of strength B, directed into the page. In the second part of the mass spectrometer shown above, ions with mass m, charge q and speed v enter a region containing only a magnetic field of strength B, directed into the page. The ions enter through a slit at S, with velocity perpendicular to the magnetic field, move in a Semi-circle radius R and hit a photographic plate at point P. Use any of the variables v, q, m, R, B as needed: A) What Is the magnitude of the magnetic force On an ion? Are the ions positive Or negative? C) What Is the centripetal force necessary to move the ions in a circle (use a combination of m, V, R)?Explanation / Answer
magnitude of magnetic force = q * v * B
ions are negative as the force is acting downward
centripetal force = m * v^2 / R
