Rutherford's scattering experiments gave the first indications that an atom consists of a small, dense, positively charged nucleus surrounded by negatively charged electrons. His experiments also allowed for a rough determination of the size of the nucleus. In this problem, you will use the uncertainty principle to get a rough idea of the kinetic energy of a particle inside the nucleus. Consider a nucleus with a diameter of roughly 5.0×10−15 meters. Part A: Consider a particle inside the nucleus. The...

If the electron were displaced from equilibrium by a distance
greater than R, would the electron oscillate? Would its motion be
simple harmonic? Explain your reasoning. (Historical note:
In 1910, the atomic nucleus was discovered, proving the Thomson
model to be incorrect. An atom's positive charge is not spread over
its volume as Thomson supposed, but is concentrated in the tiny
nucleus of radius 10^−14 to 10^−15m.)
Any solution with an explanation for this question would be
greatly appreciated.
