Two Dimensional Kinematics of an electron

Click For Summary

Homework Help Overview

The problem involves the kinematics of an electron in a cathode-ray tube, specifically focusing on its horizontal motion and the vertical displacement resulting from an upward acceleration. The original poster presents a scenario where the electron travels horizontally at a specified speed while being subjected to an upward acceleration.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the time it takes for the electron to cover a horizontal distance and question the source of the distance value provided. There is confusion regarding the completeness of the problem statement, particularly concerning the time variable necessary for calculating vertical displacement.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the problem's details. Some guidance has been offered regarding the need for complete information to proceed with the calculations. Multiple interpretations of the problem's requirements are being explored.

Contextual Notes

There is a noted lack of explicit time information in the problem, which is crucial for determining vertical displacement. Participants are encouraged to ensure all relevant details are included in the problem statement.

Homework Statement



An electron in a cathode-ray tube is traveling horizontally at 2.60×109 cm/s when deflection plates give it an upward acceleration of 5.90×1017 cm/s^2.What is its vertical displacement during this time?

Homework Equations





The Attempt at a Solution


I got this one but other than that I am so lost How long does it take for the electron to cover a horizontal distance of 6.10 cm? t =2.35×10^-9s
 
Physics news on Phys.org
Where did the 6.10 cm come from?
 
It was given to me in the original problem.
 
Wait, I'm confused. I don't see it in the problem you posted.

In fact, the problem as you posted it is incomplete. It talks about "vertical displacement during this time" but there's no time given. Why don't you post the problem again but make sure to include the whole thing this time :wink:
 
Oops...I am sorry about that.

Isn't that the same thing you posted before, though?

Sorry to not be helpful, but I'm really confused by what you're posting.
