In this problem we will examine an \electric dipole". many systems can be viewed asconsisting of equal and opposite electric charges separated by some distance (e. g. the saltmolecule nacl). thus, it is important to understand their cumulative electrical e ect ontheir surroundings. usinga= 0: 1 m andd= 1 m, determine the net electric force onq. then repeat this but used= 2 m. by what factor did the net electric force change? explainthis result. note that the distancedextends fromqto the point halfway between the othertwo charges
