    Hello clanish. Welcome to PF !

    Here is a link to the rules for this Forum: https://www.physicsforums.com/showthread.php?t=414380.

    According to the rules for Homework Help:
    "NOTE: You MUST show that you have attempted to answer your question in order to receive help. You MUST make use of the homework template, which automatically appears when a new topic is created in the homework help forums.

    On helping with questions: Any and all assistance given to homework assignments or textbook style exercises should be given only after the questioner has shown some effort in solving the problem. "​
    So as you can see, we shouldn't help until you show what you have tried.
