Derive equation of torque: G = p X E from equation U = -p[itex]\cdot[/itex]E

2. Relevant equations

G = [itex]\int x \times \rho(x)E dV[/itex]

U = [itex]\int \rho(x)x \cdot \nabla\varphi dV [/itex]

3. The attempt at a solution

I tried to figure how to represent G in a way that better express the nature of the problem. so I figured maybe G = r x F but then got stuck again...
