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 letg(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) ifnis a constant vector

g(P) = n xP/r^3

Thank you in advance
