I have always been told that a charged object will attract an uncharged on when brought close (but do not touch) the uncharged object. However, wouldn't this depend on whether the uncharged object is an insulator or an conductor? This is my reasoning, but I am not sure if it is correct: When the uncharged object is brought close to an uncharged insulator, there will not be attraction because there are no free electrons in the insulator, and the charges on the insulator will hardly move. But in the case of uncharged conductor, when the charged object is brought close but do not touch the conductor, there will be a force as the opposite charge will be brought to the front while same charge will be pushed to the back. Am I correct? Or I am confused,,,.. Any clarification will be appreciated.. Thanks.
