    What is Q in kQq/r ??

    Hey guys the textbook says Q is (+Ze) and q is (+2e) the later is 2 times the positive equivalent of an electron's charge. Though the former I'm unable to make any sense of, what is Ze??

    Thanks Cheers!!

    "Z" is a common symbol for "atomic number". It represents the number of protons. So Ze is the total charge of the nucleus.

    Considering the series of basic questions you've posted so far, may I suggest that you go to the Hyperphysics website and read through that? It appears that you're reading a textbook, but not understanding where things came from.

    Yes, and everyone is not just given fish, but also taught how to fish. You are given a resource that could be a place where you can find answers to other questions.
