Homework Help: Electric Field

  1. Apr 19, 2008 #1
    1.You are observing the effects of a single point charge with magnitude of +4.3 µC.

    2. Draw a diagram of the electric field around this charge. Be sure to indicate the direction of electric field lines.

    3. I know that the lines will point away from the charge because it is positive but i don't know how many lines to put. because it says that if its positive but the charge is high there will be alot more lines. how do i know how many lines to put??

    In these types of problem I don't think it matters about the number of lines since all you're supposed to do is show you understand what the field lines around a positive point charge look like.
