Static electric force is non contact force 2 Pro this which experiment done
Answers
Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other.
Explanation: Flying Plastic Bag Experiment
Remember how the Harry Potter cast levitated their feathers using the ‘Wingardium Leviosa’ charm? Now you can too with the power of static electricity!
What you will need:
a plastic rod
a piece of cloth
a light plastic bag
Steps:
Rub the surface of the rod with the cloth for 40 seconds
Flatten the plastic bag and rub the cloth against its surface for 40 seconds
Release the plastic bag and watch it levitate as you wave the rod below
How it works: (Hint: It’s not magic!)
The rod and cloth gain become negatively charged after you rub them with a cloth. As like charges repel, the plastic bag appears to repel.
