    soft or!!

    Hi, I'm having this problem and I'm wondering if any of you can figure out the solution and solve it.

    If your have n and it is a constant number and let g(P) is vector field calculate rotation of (P) and div(P)

    g(P) = nP /r^3

    then what is the rot(q) and div(q) if n is a constant vector

    g(P) = n x P /r^3

    Thank you in advance

    Sorry but I can't make any sense of this question. What is P? What is q? Please post the question exactly as it's written in your book (or wherever it has come from).
