Electric field help

  1. Apr 6, 2013 #1
    How do I draw the electric field for this?

    Draw the electric field for a positive and negative point charge positioned 5 cm from each
    other. Do the same for two negative charges the same distance apart and finally two positive
    charges the same distance apart.
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Tell us a little about what you know about the problem.

    i have to make a diagram or chart of a few of these sequences that shows the relationship between the electric fields using rays and pointing towards or from the charge in each of the problems

    Here are a few hint questions.
    What is the direction of the electric field from a positive and negative charge?
    How do you find the value of the electric field a distance from a charge.
    Since the fields from the charges have magnitude and direction, try doing a vector addition.
    Do this for a few points and you will see the general direction of the field lines.
