The Essay on Formal lab report on ionic and covalent compounds. Lynn University. Thus, the positive charge is attracted to the rod more strongly than the negative charge is repelled, and there is an overall net attraction. This is explained by the like charges repel principle. The plate acquires an excess of positive charge (since electrons have left this once neutral region) and the support/needle acquires an excess of negative charge (since electrons have entered this once neutral region). Start each observation with the section number and step number (e.g., I-2 for the step below). In the conductor, electrons are free to move through the material, and some of them are repelled over to the opposite surface of the conductor, leaving the surface near the negative rod with a net positive charge. Uncategorized coulomb's law experiment lab report conclusion.
