Document Summary
Does not mean we have no charge, just that we are balanced. The structure of a neutron actually has positive and negative charged components that equal out to zero. There are two kinds of electric charge: positive and negative. A body is electrically neutral (uncharged) if the sum of all the charges in the body is zero. The elementary, or fundamental, unit of charge is e = 1. 602 x 10-19 c. The si unit of charge is the coulomb (c ). The force decreases with increasing distance between charges. A body is electrically neutral when they have equal amount of free moving negative and positive charged components. An object can become polarized if the charges within it can be separated (or rearranged) By holding a charged rod near the body, the object can be polarized. The negative components get pulled towards the positive rod, and the positive components get pushed from the positive rod.
