1. The problem statement, all variables and given/known data Two point charges are placed on the x axis. The charge + 5 q is at x =1.50m , and the charge −q is at x= -1.50m . There is a point on the x axis between the two charges where the electric potential is zero. Where is this point? The electric potential also vanishes in one of the following regions: Region 1, 10.0m>x>1.50m ; region 2, -1.50m >x> - 10.0m. Identify the appropriate region. Find the value here. 2. Relevant equations V= kq/r 3. The attempt at a solution For part a) 0 = -1/x + 5/(3-x) Solve for x, i got 0.5, which is from -1.50 I don't understand how to get the second region.
