What you'll learn

  1. One circle: A half circle: it lands one diameter away
  2. Speed it up first: Voltage, then a circle: V = qB²r²/2m
  3. A heavy ion: The same voltage: r grows as √m
  4. Same speed: The same speed: r ∝ m/q
  5. Same energy: The same energy: r = √(2mK) / qB
  6. Same voltage: The same voltage: r ∝ √(m/q)
  7. Leave the strip: The exit angle: sin α = d / r
