Question

Your physics assignment is to figure out a way to use electricity to launch a small 6.0-cm-long plastic, 1.0 gram drink stirrer. You decide that you'll charge the little plastic rod by rubbing it with fur, then hold it near a long, charged wire. When you let go, the electric force of the wire on the plastic rod will shoot it away. Suppose you can charge the plastic stirrer to 14.0 nC and that the linear charge density of the long wire is 1.0×10⁻⁷C/m:

What is the electric force on the plastic stirrer if the end closest to the wire is 2.0 cm away?

1. (5 points) Create a VPython that will computationally calculate the electric force on the plastic stirrer if the end closest to the wire is 2.0cm away? Your program can use the analytically determined E-field from the very long charged wire. But in the process of finding the net force on the stirrer you must calculate the force on each individual dq in the stirrer.
