Homework Help Overview

The original poster attempts to calculate the magnitude of the force on an electron moving in a magnetic field, specifically focusing on the interaction between the electron's velocity and the magnetic field strength.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the application of the formula f = qvBsin(θ) and question the values used for charge and angle. There is also a focus on ensuring the correct mode is set on the calculator.

Discussion Status

Some participants have offered guidance regarding the inclusion of the magnetic field strength and the correct value for charge. Multiple interpretations of the problem are being explored, particularly concerning the values used in calculations.

Contextual Notes

There is mention of potential errors in the values for charge and the mode of the calculator, which may affect the calculations. The original poster's results have not aligned with expectations, indicating possible misunderstandings or miscalculations.

It looks like you didn't include B.
 
oh thank you after i include B i still get the wrong answer. i get 2.68E-22
 
I just noticed you're not using the right value for q, and make sure your calculator is in degrees mode.
