Homework Help: Electric potential at the center of meter stick

  1. Sep 11, 2012 #1
    Two 3.00-μC charges are at the ends of a meter stick. Find the electrical potential for the center of the meter stick.


    I just want to confirm my answer here. What I did is solve this for both charges in the equation above using r = 0.5m q= 3.00 uC. So I factored out k/r since they were the same for both charges, summed the charges, and then multiplied by k/r. My number isn't coming out correct for some reason and I believe it may just be calculator error. Thanks!
