Two chloride ions and two sodium ions are in water, the “effective charge” on the chloride ions (Cl−) is −2.00 × 10−21 C and that of the sodium ions (Na+) is +2.00 × 10−21 C. (The effective charge is a way to account for the partial shielding due to nearby water molecules.) Assume that all four ions are coplanar.             where a = 0.280 nm, b = 0.760 nm, and c = 0.460 nm.         What is the direction of electric force on the chloride ion in the lower right-hand corner in the diagram? Enter the angle in degrees where positive indicates above the negative x-axis and negative indicates below the positive x-axis.   °         Prev
