Some ions are being arranged along the circumference of a circle with radius R = 14 cm. First, a Fe+ ion is fixed in place at the 12 o'clock position. Then an 02- ion is fixed in place at a position that is 0 = 24 clockwise from the 6 o'clock position. If we follow the convention that the electric potential is zero when we are infinitely far away from any charges, then what is the electric potential V at the 6 o'clock position? The symbolic answer should be stated in terms of R, 0, k, and e, though not all of these quantities may be needed.
