Are Z distributions always symmetric? Web2. Let f(x) ≥ 0 be a smooth, compactly supported function on R3. The gravitional force at p ∈ R3 coming from the mass distribution f(x) dx is given by the vector F(p) = Z R3 x−p x−p 3 f(x) dx . (a) Show that F(x) = ∇φ for a suitable function φ(x). (b) Show that if f(x) vanishes on a neighborhood of p, then φ is harmonic near p.
