Section23.5Challenge - Electric Energy and Potential
Explanation23.5.1.Electric Potential of a Wire.
Figure23.5.1.A charged wire lies along the y-axis with one end starting at the origin.
The wire shown above has one end located at the origin. The wire has length \(L\) and a non-uniform charge density \(\lambda = \frac{q_o y}{L^2}\text{.}\) Points A and B are located a distance \(x_o\) from the top and bottom ends of the wire, respectively.
Is the electric potential at point A greater than, less than, or equal to the electric potential at point B?
A*R*C*S23.5.2.Charged Ring.
A uniformly charged ring with total charge \(-q_o\) and radius \(R\) is located in the \(xy\)-plane. Determine the electric potential a distance \(z\) above the center of the ring
Tip.
Evaluate your answer in at least two special cases
SubsectionMetacognitive Reflection
Compare the electric potential energy to the gravitational potential energy. Identify similar equations and write a few sentences commenting on their differences.
