Electrostatic force is the force that exists between two or more static charges. Electrostatic force is a part of one of the fundamental forces, namely electromagnetic force. This force is everywhere. From the core of an atom to the distant star, you can imagine. This ever pervading force is silently controlling not only our lives but also the fate of each and every charge particles of this universe.
Below we have mentioned 8 examples of the electrostatic force around you.
Examples of Electrostatic Force
- After combing, comb attracts paper pieces. This is especially visible in the winter season when the weather becomes dry.
- Amber attracts lightweight particles like paper flakes after rubbing with silk.
- A Balloon gets attracted to another balloon when one of them is rubbed with dry hair.
- Lightning occurs when clouds collide with each other. This is also an example of natural phenomena due to electrostatic force.
- Deflection of hair after touching van de Graff generator. (See featured image)
- Your craft glue or any adhesive works due to electrostatic force.
- Operation of Photocopier or Laser Printer depends on this force.
- Ionic bonding in NaCl is another example.
Questions related to examples of electrostatic force:
Does electrostatic force depend on the mass?
No. It only depends on the charge. Like charges repel each other, and opposite charges attract.
Does electrostatic force depend on the distance?
Yes. It is inversely proportional to the square of the distance between two charged particles.
Does electrostatic force act in the absence of air?
