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]

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