Potential difference in an electron

Click For Summary

Homework Help Overview

The discussion revolves around a problem in electrostatics, specifically concerning the potential difference between two plates when an electron is accelerated by an electric field, acquiring a certain amount of kinetic energy.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to calculate the potential difference using the relationship between work done and charge. Some participants question the relevance of the velocity of the electron in this context, while others inquire about the implications of the product of charge and potential difference.

Discussion Status

Homework Statement



An electron acquires 3.01e-16 J of kinetic energy when it is accelerated by an electric field from plate A to plate B. What is the potential difference between the plates?
_____V

Homework Equations



- (Wba / q ) = V

The Attempt at a Solution



- (3.01e-16 / 1.6e-19) = V
V = -1881.25

What does the product of the charge of the electron and the pd of the plates give you?
 
would those give me the velocity between the two plates?
 
Why do you need the velocity for?
