  We will examine the electrostatic properties of exceptional and regular zeros
of $X_m$-Laguerre and $X_m$-Jacobi polynomials. Since there is a close
connection between the electrostatic properties of the zeros and the stability
of interpolation on the system of zeros, we can deduce an Egerv\'ary-Tur\' an
type result as well. The limit of the energy on the regular zeros are also
investigated.
