Hello, I am needing help with the following Coulumb's law lab question:
The video shows two metal spheres, one sitting on a scale and the other suspended from a string. When the spheres are charged they exert forces on each other. We can measure the force on the lower sphere by looking at the scale reading. Watch the video and record distance and force data when the sphere is paused and the scale stabilizes. The distance data need only be recorded once since the same distances (approximately) are used for each trial.Our goal is to develop a mathematical relationship between the force exerted on the spheres and the distance between them.
1: Compare the techniques used to charge spheres positively and negatively. Explain how these charges are achieved.
Hint:
Keep in mind:
- Positively charged nuclei are locked into fixed positions in a solid. Only negatively charged electrons are mobile.
- Like charges repel and opposite charges attract.
