Figure, shown below, shows three situations involving a charged particle and a uniformly charged spherical shell. The charges and radii of the shells are indicated in the figure. If F₁ , F₂ and F₃ are the magnitudes of the forces on the particle due to the presence of the shell in situations (I), (II) and (III), respectively, then
