Help quick please! Rutherford used positively charged particles to investigate the structure of the atom. The results surprised him, and he developed the atomic model shown below.
A purple ball in the center surrounded by overlapping concentric black ovals, each with a small green ball on each of the 6 ovals.
What surprising result is explained using this model?

An electron moves with a constant horizontal velocity of 3.0 ร 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
