Finding electric field

  1. Feb 13, 2010 #1
    Let a point charge Q1- 25 nc be located at (4,-2,7) and Q2= 60nc be at (-3,4,-2).
    a)Find E at (1,2,3) b)at what point on the y axis is Ex=0

    For part a) i found the electric field to be 68.92x-32.319y+85.936z

    b)would electric field on Ex be 0 at y=32.319??

    Can you show the work you did to get those answers? It is easier to help if you do that.
