Combining Proportionality Statements

  1. Sep 14, 2010 #1
    1. The problem statement, all variables and given/known data

    Combine the proportionality statements for R and d and R and l to form one statement relating R, d, and l.


    2. Relevant equations

    I already know that R∝(1/d squared) and R∝l



    3. The attempt at a solution

    I thought it was R∝ (l/d squared), but that seems too easy lol.


    Please help n_n

    Hello qswdefrg,

    Welcome to Physics Forums!
    If by that you mean Rl/(d2), then it certainly sounds reasonable to me. :approve:

    So it turns out I was right after all! And I finished the assignment.

    ...

    I just realized now that this wasn't a physics problem at all; just pure common sense ;___;
