A velocity selector consists of two parallel plates with an electric field strength of 1600 N/C. Alpha particles with a velocity of vi = 2100 m/s and v2 = 3300 m/s are to be fired horizontally into the middle of the velocity selector (as shown below). The alpha particlestravelling at 3300 m/s are to pass through the velocity selector undeflected, while the slower travelling alpha particles will collide with one of the plates.

In my laboratory, if I notice my vacuum system has a leak to atmosphere, I use a mass spectrometer to find the leak. I connect my vacuum system to the mass spectrometer, and spray my systems walls with helium. If the mass spectrometer reads helium when I spray a particular wall of my system, I can pinpoint where the leak is. Suppose an ionized helium atom has a mass of 6.6 x 10^-27 kg and a speed of 4.4 x 10 ^5 m/s as it moves into the mass spectrometer. It moves perpendicular to a .75 T magnetic field on a circular path that has a .012-m radius. Determine whether the charge of the ionized atom is +e or +2e.
All of the high-energy physics colliders built in recent decades have collided one beam of particles with a second beam traveling in the opposite direction. For example, the Large Hadron Collider at CERN sends particles of opposite charges around a ring, with one beam traveling clockwise and the second traveling counterclockwise. Technically it is much more difficult to get the two beams to collide with one another in this way as compared to just having one beam slamming into a stationary target, yet this still how colliders are built. Consider the following two situations. In the first picture, (the modern collider design), two equal mass m particles collide, each with total energy Ecollider, to produce some exotic new particle of mass M, at rest. Conservation of energy says that 2Ecollider = Mc^2. On the other hand, in the second picture (the fixed-target design), a particle of mass m with energy Efixed hits an identical mass particle at rest, producing the same exotic new…
