 Before we go to Mars we need to test safety features such as the ability to stop harmful radiation. You are part of a team that is designing a “force” field that will deflect alpha particles. You need to create a design that will stop alpha particles that are shooting directly at a group of astronauts who are creating a habitat on the moon as a test run. The alpha particles are traveling with a speed of 1.28 * $10^{+07}$ m/s from very far away.

 For this problem, it is easy to get trapped in the numbers without thinking about what is actually going on in this problem. Push student to talk through qualitatively what it is they are trying to solve for in this situation first.

   * **Question:** What does the free body (force) diagram look like for the large and small charge?
-  * **Answer:** (They may have these diagrams from their process already.) From the diagrams it should be clear why the big cloud does not move/change speeds (there are two balancing forces - no change in momentum) but the small cloud does (only one force - so the small cloud has an acceleration or a changing momentum).
