Question

An Fe3+ ion is located 400 nm (400 ✕ 10−9 m, about 4000 atomic diameters) from a Cl− ion, as shown in the figure below (ions not shown to scale). (a) Determine the magnitude and direction of the electric field EA at location A, r = 116 nm to the left of the Cl− ion. magnitude 3.74e5 Incorrect: Your answer is incorrect. N/C direction Correct: Your answer is correct. (b) Determine the magnitude and direction of the electric field EB at location B, r = 116 nm to the right of the Cl− ion. magnitude 9.4e4 Incorrect: Your answer is incorrect. N/C direction Correct: Your answer is correct. (c) If an electron is placed at location A, what are the magnitude and direction of the force on the electron? magnitude 2.4e-14 Incorrect: Your answer is incorrect. N direction
