Homework Help: In an experiment similar to Thomson's

  1. Apr 21, 2009 #1
    1. The problem statement, all variables and given/known data

    In an experiment similar to Thomson's, charged particles are observed to travel through a magnetic field of 0.040T with a radius of curvature of 0.20m. The path of these particles is made straight again when an electric field is introduced by two parallel plates. The plates are separated by 10cm and have a potential difference of 200V across them. Calculate the charge-to-mass ratio of these particles.

    2. Relevant equations

    3. The attempt at a solution
    I am not sure on how to start this question. I have been given the answer just am not sure how to show the work.
