1. The problem statement, all variables and given/known data 24 identical positive charges, each has a magnitude 2.0 microCoulombs equally spaced along a circle with a radius of 0.4 m which lies in the y-z plane. a)determine the electric field at a point 1 meter away from the circle's center along the x-axis. b) Find the electric potential at the point P c) What is the electric field and potential at the circle's center? 2. Relevant equations E = kQ/R^2 V = kQ/R 3. The attempt at a solution I know that symmetry applies, but I'm not sure exactly how. A) 2 sigfigs Positive - radiate outwards to point P E = kQ/R^2 - Should I calculate the charge for each individual charge for 12 of them and multiply that answer by 2? - Or can I calculate the field for one and multiply by 24? C) The electric field at the center of the circle is 0, I think, because the charges cancel each other out. D) But does that mean that the potential at the center is 0 as well?
