Calculating Potential Energy in a Parallel Plate Capacitor

Click For Summary

Homework Help Overview

The problem involves calculating the potential energy of a point charge suspended between the plates of a parallel plate capacitor. The scenario includes a mass, charge, angle of deflection, and separation distance between the plates.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the initial equations related to potential energy and forces acting on the charge. There is uncertainty about how to start the calculations, with one participant suggesting the need for a diagram to clarify the setup.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the problem. Some guidance has been offered regarding the need for a visual representation, while questions about the specifics of the pendulum's length remain unresolved.

Contextual Notes

Participants note that the problem does not provide the length of the pendulum, which may be relevant for further calculations. The focus is on the given angle and distances between the plates.

Homework Statement



A point charge mass of 0.0788kg and q charge= +6.62 uc is supended by a thread between the vertical plates of a parallege capacitor. If the angle of delflectionis 23.7 degress and the separation between the plates is d= 0.0242m, what's the potential energy?

Homework Equations


v=w/q


The Attempt at a Solution


not sure, where to begin but...
V= w/q
w=1/2cv sq
F= keqq/r
F= 8.99e9 (6.62e-6)/.0242 sq

I think you'll need to draw a picture here.
 


i have 2 parallel lines then the distance btw the lines is d= .0242, then a pendulum ball @ an angle

What's the length of the pendulum?
 


there isn't it only tells u the angle and the distances btw the 2 parallel lines
