Homework Help: Electric Field due to Multiple Point Charges

  1. Sep 8, 2009 #1
    1. The problem statement, all variables and given/known data

    Two point charges are placed on the x axis. The first charge, q1 = 8.00 nC, is placed a distance 16.0 m from the origin along the positive x axis; the second charge, q2 = 6.00 nC, is placed a distance 9.00 m from the origin along the negative x axis.

    Calculate the electric field at point A, located at coordinates (0 m, 12.0 m).

    2. Relevant equations


    Calculate the distance from each charge to point A

    Determine the directions of the electric fields

    Calculate the components of E

    Give the x and y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant figures.

    3. The attempt at a solution

    I am not sure what to do.. I am getting confused with the components.. Can someone show m how to do this?

    Show your attempt. The components of E are Ecosθ and Εsinθ.
