    Procedure:
    1.Write a program to simulate the interaction of multiple charges in a free space.
    2.The charge and position carry by each point charges as follows

    Q1 = [tex]5\mu C[/tex] at the position(9,6,8)
    Q2 = [tex]9\mu C[/tex] at the position(6,8,5)
    Q3 = [tex]6\mu C[/tex] at the position(8,5,9)
    Q4 = [tex]8\mu C[/tex] at the position(5,9,6)

    3.Find the resultant electric field aon a [tex]7\mu C[/tex] point charce at (-1,4,8)

    4.Result of electric must in the form of [tex]A_{x}\hat{a}_{x}+A_{y}\hat{a}_{y}+A_{z}\hat{a}_{z}[/tex]

    5.Write explanation of the program listing.

    PLEASE!!!!PLEASE!!!Anyone know how to do it,please help me write this program!!Thank you....

    By simulate Im gonna assume you are saying calculate.

    In this case you will need an array of values for C

    eg. This is how you create an array.

    Goto file>new>mfile

    C=[1 2 3 4 5 6 7 8 9 10]; etc

    then you need to identify what mew is by;

    mew=(Whatever mew is);

    then type in the formula such as

    Q=mew*C;

    when you run this it should give you another array with the answers up in the command window.

    How come you have been asked to use matlab if you have never done it before?

    hope this helps for Q1
