Purpose The purpose of the lab is to map the equipotential lines and field lines for two- dimensional charge configurations. Theory To find the magnitude of the electrostatic force between two point charges Q and q is given by Coulomb’s law: o = F kQqr2 o Where r is the distance between the charges and the constant = . × k 9 00 109 Nm2C2 . Like charges repel, and like unlike charges attract. The magnitude of the electric field is defined as the electrical force per unit charge. o = = E Fq kQr2 We can also can write a unit vector equation that gives both the magnitude and direction of the electric field E , by using the unit vector = r rr o = E Qr2r Note that, by definition the electric field of a point charge always points away from a positive charge but towards a negative charge. The work done by an electric field in moving a unit charge from point A to point
