A conducting sphere is charged up such that the potential on its surface is 100 V (relative to infinity). If the sphere’s radius were half as large, but the charge on the sphere were the same, what would be the potential on the surface relative to infinity?

In a certain region, the electric potential due to a charge distribution is given by the equation V(x,y,z) = 1.5x2y2 + 0.5yz3- z3x, where x, y, and z are measured in meters and V is in volts. Calculate the magnitude of the electric field vector at the position (x,y,z) = (1.0, 1.0, 1.0).

A conducting sphere is charged up such that the potential on its surface is 100 V (relative to infinity). If the sphere’s radius were twice as large, and the charge on the sphere was double, what would be the potential on the surface relative to infinity?

What are some of the ways people try to reduce cognitive dissonance?  Define this concept and how it can be used to explain how someone who believes smoking causes lung cancer continues to smoke (while understanding the biological aspects of addiction).
