1. The problem statement, all variables and given/known data A +3.00 mirco C charge is separated 4.00cm from a +4.50 mirco C charge. Is the electrical potential zero anywhere? If so, find the location. Explain how the problem changes if the 4.50 mirco C charge is negative. 2. Relevant equations V = E/q V = w/q v = kq/r 3. The attempt at a solution My teacher just taught us this today and gave us a horrible explaination of what electrical potential is so my classmates and I have no idea what to do.
