A hard rubber comb can be given a negative electric charge by rubbing it against a variety of materials, including human hair. Suppose an atmospheric ion having a charge of +1.60×10−19 C is resting at a point near the comb where the strength of the field is 973 N/C. (a) What is the magnitude of the force that the field exerts on the ion? (b) Will the ion move toward the comb or away from the comb?
