Find the potential at the sodium ion, Na^+, which is surrounded by two chloride ions, Cl⁻, and a calcium ion, Ca²⁺, in water as shown in the diagram. The effective charge of the positive sodium ion in water is 2.0 × 10⁻²¹ C, of the negative chlorine ion is −2.0 × 10⁻²¹ C, and of the positive calcium ion is 4.0 × 10⁻²¹ C.
