An iodine (-1) and a chloride ion (-1) interact in a vaccum. a. What is the force which each exerts on the other from a distance of 2.0 x 10^-9 m? b. What is the eletric field that the iodine ion experiences from the chloride ion? toward which ion does the electrical field vector point? c. By what factor must the chloride ion be moved so that it experiences 1/64 of the electric field iodine ion as in part b? This is work from the spring that I am finishing up and I can not rember how to go about solving this problem. Could someone please help me? I just need a poitn in the right direction. I am pretty sure that the forces they exert on each other would be equal but beyond that I am not sure how to go about the problem.
