M3 Laboratory Report 2 Worksheet

PhET Simulation: Charges and Fields

Instructions

• Before you start to work on this worksheet, review the M3.0 Laboratory Report 2 Instructions
• Submit completed work to the M3.0 Laboratory Report 2 dropbox. See the Schedule and Course Rubrics in the Syllabus Module for due dates and grading information.

Objectives:

1. Investigate the concept for Electric field and its dependence of distance and magnitude of charge.

2. Visualize Electric field lines and Electric field vector.

3. Determine net Electric field due to multiple charges and in different symmetry.

Pre-Lab Activities:

1. Open the simulation using the link to PhET Interactive Simulations at the University of Colorado Boulder:

PhET Interactive Simulations

1. Explore the options available in the simulator:
   • drag a charge from the box at the bottom and place it on the screen
   • drag on the screen the measuring tape you will be using to measure the distances
   • drag and place at some distance from the charge the yellow sensor
