How much work must you do to move an electron from A to B? The rectangle is 14.6 cm high and 24.8 cm wide. Remember that negative work means that we can get work out of the process.
In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having
charge +2e and mass 6.64 x 10-27 kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of an atom's mass is in a very small nucleus, with electrons in
orbit around it. Assume an alpha particle, initially very far from a stationary gold nucleus, is fired with a velocity of 2.98 × 107 m/s directly toward the nucleus (charge +79e). What is the smallest distance
between the alpha particle and the nucleus before the alpha particle reverses direction? Assume the gold nucleus remains stationary.
