qq= 1 Objective (5 pts)In this is lab, we willLearn the concept of electric field lines and equipotentiaExperimentally search points in an electric field, having the same potential (equipotential lines)Use the equipotential lines for drawing electric fieldCalculate the magnitude of the electric field2 Backgroundand theory(10 pts)2.1 Electric Filed (2.5 pts)An electric field consists of a distribution of vectors in every pointaround an isolated charged of object, as a charged rod. Any particle of positive charge q0 , placed at any point, P, in the vicinity of a object, is subject to an electric force, F~: at any pointP In its vicinity, the charged ob ject, an electric field, E~ , that creates an electric force, F~ , acting on the test charge q0 . This electric field is defined as:E~ = Fq02.2 Electric field lines(2.5 Michael Faraday, who introduced the idea of electric fields in the 19th century, thoughtof the space around acharged object as filled with lines of force also called electric field lines. Electric field lines are for visualizing the pattern of the of electric field. The field lines are related to the electric field by Lines force are the path traversed by a test charge as it moves from one pointto another in the field. The electric field is tangentin every pointof lssuch chargedsets up~pts)useful this:
