SUMMARY

An electron moving horizontally east in an upward electric field experiences a force that acts vertically downward. This is due to the negative charge of the electron, which causes the force to be directed opposite to the direction of the electric field. The relevant equation for understanding this interaction is vector F = vector E * q, where F is the force, E is the electric field, and q is the charge of the electron. Therefore, the correct answer to the homework question is option c: vertically downward.

PREREQUISITES
  • Understanding of electric fields and forces
  • Knowledge of charge polarity and its effects on force direction
  • Familiarity with vector notation in physics
  • Basic grasp of Newton's laws of motion
NEXT STEPS
  • Study the concept of electric fields and their effects on charged particles
  • Learn about the relationship between charge, electric field, and force using vector analysis
  • Explore the implications of charge polarity in different electric field configurations
  • Review Newton's laws of motion in the context of charged particle dynamics
USEFUL FOR

Students studying physics, particularly those focusing on electromagnetism, as well as educators seeking to clarify concepts related to electric forces and charge interactions.

Homework Statement



An electron is moving horizontally east in an electric field that points vertically upward. The electric force on the electron is

a.zero
b.vertically upward
c.vertically downward
d.to the east


Homework Equations



This is really a conceptual question. (Perhaps vector F = vector E*q)


The Attempt at a Solution



Is the answer c.vertically downward?? An electron has a negative charge, so the force on the charge is in an opposite direction from the electric field, which is vertically upward?

Thanks.
