Worksheet - Exp 14: Electric Fields and Potentials Objective: To map the equipotential lines and electric field lines of point charges and parallel plates; to measure the strength of an electric field and explore its relationship to potential. Theory:
Creating and Measuring Electric Fields. At what distance from a 2.4–pC charge will the electric field be 360 N/C? What will happen to the electric potential energy of a charged particle when it is released in an electric field and allowed to move freely? The nucleus of a lead atom has 82 protons.
1. A source charge q exerts an electrical force of 4.0 x 10-17 N on an electron located at point P. What is the electric field strength at point P? 2. How much force is exerted on an alpha particle (see sheet #1) by an electric field when the α particle is placed at a location where the electric field strength is 75 N/C? 3.

How can the magnitude of an electric field be measured? 4. Is the following statement true or false? The direction of an electric field at any point, by convention, is the direction of the electrical ...
Use these results and symmetry to find the electric field at as many points as possible without additional calculation. Write your results on or near the points. Sketch the approximate magnitude and direction of the field at these points.
The electric constant is used in Coulomb's law to find the force acting between two point charges separated by a distance . Two students wondered why all the example problems shown by their teacher used the electric
