• Resumen

  • The motion of charges around a centrally charged object is often compared to gravitational orbits (such as satellites around planets). Recently, a video1 taken by astronaut Don Pettit onboard the International Space Station shows water droplets orbiting a charged knitting needle. Here we attempt to model this motion and estimate the charges on the objects involved in this system.
