Homework Help: Electric Field Strength charges

  1. Apr 21, 2008 #1
    1. The problem statement, all variables and given/known data
    Charge A has 10 electric field lines coming out, Charge B has 20 lines coming out, and Charge C has 30 lines coming in. Which pair of these charges will have the largest force between them if placed one cm apart?


    2. Relevant equations



    3. The attempt at a solution
    Is it B and C just because they have the most amount of lines??

    Yes. WHen drawing electric field lines, the number of lines are only a relative quantification of the field strength. If field lines are properly drawn, then 3 x the number of lines emanating from a charge indicates a charge 3 x as great.
