- An alpha particle (He++) is passing horizontally over your paper from right to left at 7.73 x 10^6 m/s when a large, uniform magnetic field of 12.44 T out of the paper is immediately turned on. The ion is caught in a circular path. An accurate and detailed sketch of the ion, magnetic field, and path of the ion is recommendedk = 8.99 x 109 Nm2/C2, me = 9.11 x 10 – 31 kg, e = 1.6 x 10 – 19 C, mp = 1.67 x 10 – 27 kgAtom 1 of mass 35 u and atom 2 of mass 37 u are both singly ionized with a charge of +e. After being introduced into a mass spectrometer (see the figure below) and accelerated from rest through a potential difference V = 7.4 kV, each ion follows a circular path in a uniform magnetic field of magnitude B = 0.30 T. What is Δx, the distance between the points where the ions strike the detector? _____________m (please show units so that I can follow easier)
- 1 Singly-charged lithium ions, liberated from a heated anode are accelerated by a difference of 400 V between anode and cathode. They then pass through a hole in the cathode into a uniform magnetic field perpendicular to their direction of motion.

Determine the required magnitude and direction of an electric field E that will allow the alpha particle to continue to move along the x axis.The Bainbridge spectrometer works by ionizing particles, sending them through a velocity selector, and then detecting a given charge-to-mass ratio based on its trajectory in a uniform magnetic field (See Ch 11.7 in your book). Suppose your spectrometer works by altering the electric field of the velocity selector to scan for ions.
