3. Electric field hockey:

Now you will explore how a charge arrangement affects the motion of a single. The objective is to arrange

charges such that a positive charge will be deflected around obstacles and land in the goal.

If using the HTML5 program, you should complete the two levels following the practice round. (The first

level involves navigating around a red rectangular block; the second level involves navigating around the

cowhide pattern shown on the opening webpage for the program. For both cases, take a screenshot of

your final charge arrangement (with the charge in the goal) and attach it to this lab handout.

If using the PhET Electric Field Hockey program (using Java): after doing the practice round, complete

difficulty levels 1 and 2. Turn on the show electric field option. Attach screenshots showing your

successful completion of those two levels (resulting in a collision with the goal). [Note, this program is a

bit more challenging than the HTML5 version.] Level 3 is much more difficult than levels 1 and 2. Attempt

it at your discretion.
