Motion of a charged partcile in eletric fields help

Click For Summary

Homework Help Overview

The discussion revolves around the motion of a charged particle, specifically an electron, in an electric field. The original poster is attempting to determine the appropriate formula to calculate the acceleration of the electron given a uniform electric field strength.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss using Newton's laws and the relationship between force and electric field. The original poster questions the need for distance between plates to calculate the electric field and acceleration.

Discussion Status

The discussion is ongoing, with some participants providing guidance on using the given electric field strength. There is an acknowledgment of the original poster's realization about the simplicity of the problem, but further clarification on the use of formulas is still being sought.

Contextual Notes

The original poster notes a lack of information regarding the distance between the plates, which they believe is necessary for their calculations.

Hello.
I was completing some homework when I came stuck on a question. I have no idea which formula to use. The information I've been given is : An eletron, initally at rest, accelerated by a uniform field of 10^6 NC^-1 (By the way, ^ represents to the power of).
The question is "What is the acceleration of the electron"
Now, I am not looking for answers but which formula to use.

This would be of much help, thank you.

Use the information given to find the force and Newton's laws will take care of the rest.
 
Yikes, sorry for wasting your time, I just realized that and how easy it was. Sorry.
 
Just another quick question ~ For the force I was going to use : F=Eq but for E it is E=/\V / D
And I haven't been given a distance between the two plates.

And to work out acceleration I was going to use a=Eq/m but I need to work out E.
