Electrostatics: Finding force experienced by charge

Click For Summary
SUMMARY

The discussion focuses on calculating the force experienced by a charge of 3 microcoulombs using electrostatic principles. Participants emphasize the need to apply trigonometry to determine the angle theta at point P, which is essential for finding the resultant vector's magnitude. The Pythagorean theorem is utilized to establish the triangle's sides, but the challenge lies in calculating the angle for accurate force determination. Clear understanding of trigonometric functions is crucial for solving this problem.

PREREQUISITES
  • Understanding of electrostatic forces and Coulomb's law
  • Proficiency in trigonometry, particularly in calculating angles and vector components
  • Familiarity with the Pythagorean theorem

1. Find the magnitude and direction of the force experienced by the charge of 3microcoulombs.

Homework Equations


After subtending forces of both the particles on the third one, we need to find the aggregate magnitude of the charge experienced by it.

The Attempt at a Solution


I was able to find all the sides of the triangle created using using the Pythagoras theorem but am not able to find the angle theta at point P to find the magnitude of the resultant Vector. That should be it right? Thanks.[/B]

You have a right angled triangle with all the sides known.
You can find ∠APO using elementary trigonometry.
Have you studied trigonometry?
