Specific charge

    hi
    this is probably basic physics but how do u work out specific charge of say the nucleus of a carbon atom?
    thanks

    Welcome to PF marco123,

    Well what is the definition of specific charge?

    Not quite, it is the charge to mass ratio of the nucleus. So all you need to do is determine the charge and mass of the nucleus and then find the ratio of these two quantities. In the case of carbon, there are two common isotopes so you would need to decide which isotope you wish to find the specific charge of.

    That's entirely up to you. Of course if you were asked such a question, say in a homework, it would usually specify which isotope to use.
