SUMMARY

The influence of electrostatics on water is significant, particularly in its role as a dielectric material. Water exhibits a dielectric constant ranging from 30 to 90, which varies with temperature. Electrostatic fields cause field lines to bend towards water, indicating that charged objects are attracted to it. Practical demonstrations, such as using a charged object to attract a stream of water, effectively illustrate this phenomenon.

PREREQUISITES
  • Understanding of dielectric materials
  • Basic knowledge of electrostatic fields
  • Familiarity with the concept of dielectric constant
  • Experience with simple physics demonstrations
NEXT STEPS
  • Research the dielectric properties of water at varying temperatures
  • Explore the applications of electrostatics in fluid dynamics
  • Learn about the effects of electrostatic fields on different materials
  • Investigate practical experiments demonstrating electrostatic attraction
USEFUL FOR

Students in physics, educators conducting demonstrations, and researchers interested in the properties of water and electrostatics.

Do you mean electrostatic fields? In that case water reacts very strongly as a dielectric. In fact, for static fields, water has a dielectric constant of between 30 to 90 depending on the temperature. Fields lines outside the water will bend towards the water (indicating charged objects will be attracted), and field lines inside the water will be weakened. You can do a fun demonstration of this. http://www.youtube.com/watch?v=HVLZ8TRNL9g" and rub it on your hair to charge it up. Then hold it near but not touching the stream of water coming out of a regular sink facet and it will attract the water. It also works with a plastic comb that you have charged up by combing your hair.
