Speed of a beryllium nuceleus after acceleration

  1. Apr 19, 2015 #1
    1. The problem statement, all variables and given/known data
    A beryllium nucleus is accelerated over a voltage drop of 200 V. Calculate the speed of the particle as it leaves the accelerator.

    2. Relevant equations
    Electric field strength in a capacitor? (E=U/d).
    Working force in an electric field? (F=q*E)

    3. The attempt at a solution
    I tried fitting this problem into electric field theory, but that requires the particle to have a charge - else it should not be influenced. The only property of a beryllium nucleus I know is its mass. I did a quick estimation of 1.4966*10^-23 grams (dividing it's atomic weight by one mole).

    How can I proceed with this problem?

    The beryllium nucleus does have a charge! "Nucleus" = protons + neutrons but no electrons!
