Abstract: Let $ {M^n}$ be a compact differentiable manifold and $ {R^{n + k}}$ Euclidean space. A necessary and sufficient condition is given for an immersion $ \psi :{M^n} \to {R^{n + k}}$ to be a stationary immersion for $ J = \smallint M_\psi ^n\langle x - {x_c},x - {x_c}\rangle $ dv subject to the side condition $ V = \smallint M_\psi ^n$ dv= a fixed constant, where $ {x_c}$ is the center of mass. In particular, minimal submanifolds of spheres satisfy this condition.
