Introduction and Objective of Experiment: The magnitude of the electrostatic force between two point charges Q and q is given by Coulomb’s law: F=k|Qq| r 2 where r is the distance between the charges and the Coulomb constant k=9.0∗109 N m 2 c 2 . The directions of the forces the two charges exert are always along the line joining the two point charges and like charges repel, unlike charges attract. The magnitude of the electric field is defined as the electrical force per unit charge, or E= F q(N C) . Here q is a test point charge. In the case of the electric field associated with a single-source charge Q, the magnitude of the electric field a distance r away from the source charge is [Show More]
