Electric Force: Magnitude & Direction Calc.

Click For Summary
SUMMARY

The discussion focuses on calculating the electric force experienced by a charge of −3.5 × 10−7 C in an electric field of 12 N/C. Using the equation e = Fe/q, the user determined that the electric force (Fe) is negative, indicating that the force acts in the opposite direction to the electric field. This conclusion is confirmed by the principle that a positive force aligns with the field direction, while a negative force opposes it.

PREREQUISITES
  • Understanding of electric charge and Coulomb's law
  • Familiarity with electric fields and their properties
  • Basic knowledge of vector direction in physics
  • Proficiency in algebra for manipulating equations
NEXT STEPS
  • Study the concept of electric field strength and its calculation
  • Learn about the implications of charge polarity on force direction
  • Explore vector addition in electric force calculations
  • Investigate the relationship between electric force and distance from the charge
USEFUL FOR

Students in physics courses, educators teaching electromagnetism, and anyone seeking to understand the principles of electric forces and fields.

Homework Statement


Calculate the magnitude and direction of the electric force if a charge of −3.5 × 10−7 C is placed in a field of 12 N/C


Homework Equations


e = Fe/q

The Attempt at a Solution


I just plugged in values into the equations to find Fe and my answer was negative so the force is going to the left? I was just wondering if i did this right! thank you!​

Positve force implies it is in the same direction as the field, negative in the opposite direction to the field.
