11. The only thing that would attract this stuff to the circuitry is electrostatic force . 12. In others, electrostatic forces , as in static electricity, hold the substances together. 13. Nuclei are positively charged, and thus repel each other due to the electrostatic force . 14. This motion has to be resisted by electrostatic forces from the electrodes under the tines. 15. Usually electrostatic force is small because the sample has been covered with a polymer layer. 16. :The streamers start due to electrostatic forces : attraction between positive and negative charges. 17. The ionized particles, due to the electrostatic force , are diverted towards the grounded plates. 18. The ions are positively charged, so they repel each other due to the electrostatic force . 19. Ionic compounds are rarely purely ionic, i . e . held together only by electrostatic forces . 20. The electrostatic force between two charged elementary particles is vastly greater than the corresponding gravitational force between them.
