Direction of Net Electric Field

  1. Feb 4, 2010 #1
    1. The problem statement, all variables and given/known data

    A charge of -5.66 x 10-6 coulombs exists on each of the three spheres in the figure below. Sphere B is 0.364 meters from sphere A, and sphere C is 0.276 meters from sphere A.

    b. Find the magnitude and direction of the net electric field at the location of sphere A (referenced to east being 0°, all angles between 0° and 360°).

    3. The attempt at a solution

    I got the magnitude to be 7.71 x 10 ^5 and it was correct....

    so i solved for the angle and got 60.1 degrees...

    but I am unsure of how this will correlate to the angle.... i tried adding 270 and then 360-60.1 and neither worked

    The resultant force is in the second quadrant.
    If you find the angle by using
    tanθ = - Fy/Fx , the the required angle is (180 - θ).
