1. The problem statement, all variables and given/known data A -11.5nC point charge and a +24.6nC point charge are 14.0cm apart on the x-axis. a) What is the electric potential at the point on the x-axis where the electric field is zero? - The answer is 1.58E2 V b) What is the magnitude of the electric field at the two points on the x-axis where the electric potential is zero? (Input your answers in order of increasing distance from the negative point charge.) I figured out a, but I wasn't able to get b. There should be two answers for b. 2. Relevant equations E=(kQ)/r^2 - equation 1 V=(kQ)/r - equation 2 3. The attempt at a solution I know what to do but I wasn't able to execute it. I think you have to find the value of r in equation 2 where it equals 0 and then sub that into equation 1. I'm not sure how to do this though, any help would be appreciated!
