    Operations on 2 vector fields

    Supposing we have as 2 vector fields:
    $\displaystyle F = x^2i + 2zj +3k $

    and

    $\displaystyle G = r^2e_r + 2\cos\Theta e_{\Theta} + 3\sin(2\phi) e_\phi $

    how do i perform the following operations on them?

    - $\displaystyle F\cdot r $
    - $\displaystyle F\times r $
    - |G|
    - $\displaystyle G\cdot r $

    $\displaystyle r=xi + yj + zk$
    if r is positon vector.
    with this you can find 1,2 and 4.
