Vector Field: Showing Divergence & Curl A = 0

[danai_pa]

A vector field is difined by A = f(r)r.

a) show that f(r) = constant/r^3 if divergence A equal to zero.

b) show that curl A is alway equal to zero

Do you know the equations for divergence and curl in spherical coordinates?

yes i known.

so plug it in...

i think you mean, find a divergence and curl in a spherical coordinates. vector r is represent r, theta and phe
