Lesson: Electric Potential of a Charged DiskPhysics
In this lesson, we will learn how to calculate the absolute electric potential at a given position relative to a charged disk.
Sample Question Videos
A CD disk of radius is sprayed with a charged paint so that the charge varies continually with radial distance from the center in the following manner: .
Find the potential at a point 4.0 cm above the center.
A thin conducting plane has a charge density of C/m2. An electron is placed 0.80 cm above the the plane. What is the magnitude of the acceleration of the electron?
Two square conducting plates of side length 50.0 cm are placed parallel to each other 9.0 mm apart. What magnitude electric field is generated between the plates after electrons are transferred from one plate to the other?
