The figure below shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio e/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference ΔV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector. As the accelerating voltage is slowly increased, different ions reach the detector and are measured. Typical design values are a magnetic field strength B = 0.345 T and a spacing between the entrance and exit holes d = 9.00 cm. What accelerating potential difference ΔV is required to detect the following? (Use e = -1.60218 10-19 C for the charge of an electron, and u = 1.66054 10-27 kg for atomic mass. Round your answers to six significant figures. Ignore the mass of the missing electron.)

The picture above shows part of a mass spectrometer that can be used to measure molecular charge-to-mass ratios. A charged molecule (orange circle) is ionized and accelerated through an electric potential difference into a region with a uniform magnetic field. Here the magnetic field points out of the screen. The field makes the positively charged molecules undergo circular motion as shown. By adjusting the voltage difference between the plates, one can change the radius of curvature of the charged particles...

To five significant figures, what accelerating potential difference AV is required to detect the ion 0 ? The masses of the atoms are shown in the table; the mass of the missing electron is less than 0.001 u and is not relevant at this level of precision. Use the following constants: 1 u = 1.6605 x 10-27 kg, e = 1.6022 x 10-19 C. (Figure 1) shows a mass spectrometer, an analytical instrument used to identify the various molecules in...

An Iron-Nickel sample from a meteorite was placed into a
velocity selector and mass spectrometer. Experimenters expect 3
primary isotopes: 56Fe, 58Ni, & 60Ni. Positive ions are
accelerated by an applied potential (ΔV) of 3300 Volts which is the
same potential difference used to create the electric field in the
velocity selector, where d is 1.1 cm.
Need 3 and 4.

• The figure shows the essentials of a mass spectrometer, which can be used to measure the mass of an ion; an ion of mass m (to be measured) and charge q is produced in source S. The initially stationary ion is accelerated by the electric field due to a potential difference V. The ion leaves S and enters a separator chamber in which a uniform magnetic field is perpendicular to the path of the ion. A wide detector lines...

One type of mass spectrometer accelerates ions of charge q, mass m, and initial speed zero through a potential difference ΔV. The ions then enter a magnetic field where they move in a circular path of radius r. How is the mass of the ions related to these other quantities? Express your answer in terms of the variables q, r, B, and ΔV.

Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27 × 10-25 kg. The ions are accelerated from rest through a potential difference of 2.20 kV. Then, a 0.530-T magnetic field causes the ions to follow a circular path. Determine the radius of the path.
