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).

Two large aluminum plates are separated by a distance of 2.0 cm and are held at a potential difference of 195 V. An electron enters the region between them at a speed of 3.2 × 105 m/s by passing through a small hole in the negative plate and continues moving toward the positive plate. Assume the electric field between the plates is uniform. 1. What is the electron’s speed, in meters per second, when it is 0.1 cm from the negative plate? 2. What is the electron’s speed, in meters per second, when it is 0.5 cm from the negative plate? 3. What is the electron’s speed, in meters per second, when it is 1.0 cm from the negative plate? 4.

A point charge q1= 4.00nC is placed at the origin, and a second point charge q2=-3.00nC is placed on the x-axis at x=+20.0cm. A third point charge q3= 2.00nC is to be placed on the x-axis between q1 and q2. Let the potential energy of the three charges be zero when they are infinitely far apart. a.) what is the potential energy of the system of the three charges if q3 is placed at x=+10.0 cm? b.) where should q3 be placed to make the potential energy of the system equal to zero?
