Electric Field of 2 charges on x-axis

  1. Feb 6, 2016 #1
    1. The problem statement, all variables and given/known data
    2_charges.png

    2. Relevant equations
    |E| = (Kq)/r^2

    3. The attempt at a solution
    I'm not really sure if there is a difference between part (a) and part (b)

    Hello NPM, :welcome:

    well, from your relevant equation I wouldn't be able to see a difference! You need something more, about the direction perhaps !

    Can you sketch the fields close to the charges in the two cases (there the 'other charge' hasn't got much influence) ?

    They are very different. Why? :smile:
