Your car can build up a significant static electric charge while driving at a high rate of speed due to electrons being removed from the car body by friction with the air. The potential difference developed between your car and the ground might be as large as 30kV. Model your car as a 500 pF capacitor. a) What would be the charge on your car in such a case? b) Roads are often banked in tight turns to help prevent a car from slipping as it turns at a high rate of speed in a tight turn. What if instead we chose to use "magnetic banking" on a road. What is the minimum magnetic field strength that you would need to use to cause your charged car (of mass 1000 kg) to turn in circle of radius of 100m at 25m/s? For starters, assume the tires to be frictionless (us=0).

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. fm
