How do i measure charge?

  1. Nov 8, 2004 #1
    so...i have some crazy engineering problem. anyway, part of the problem is how do i measure the charge of a molecule? i need to find the force, F = qE. i kno the electric field i am applying, but how can i physically measure the charge of the molecule? some people thought of using HPLC (high pressure liquid chromatography) which would allow for a comparison of charge against a known molecule. but...im just wondering if there's any other way to do it. thanks

    You haven't stated the problem clearly. Are you talking about a dipole molecule (like water)? Since molecules are normally electrically neutral your question doesn't make much sense.
