The basis for Rutherford's Planetary model, was the results he got from experiments.
He observed that most of the alpha particles he fired at a gold foil, passed through the foil, but only few were deflected back. So he concluded that most of the Atom would be empty space, with a positive entity at the center.
K = ∆F / ∆s = 4N / 0.08m = 50N/m
She must find her more like herself than you i guess.
