Explain the activity to demonstrate electrostatic …

Lightning is another example of electrostatic forces in everyday life, but is shown on a massive scale. When clouds rub against each other and the particles will gain a charge, and these charges want to equalise. As the wool wants to equalise its charge this is the noise and slight zap that occurs. Electrostatic force is the force two electric charges exert on each other. It operates according to Coulombs law, which states that the electrostatic force between two charges is equal to the multiplication of the magnitude of the charges divided by the square of the distance between them.

Examples of electrostatic forces:

• When we run a piece of paper with the oil in our head with the help of a comb produces electrostatic force.
• Balloons get attracted to another balloon when one of them are rubbed with hair.
