Final answer:
The question pertains to a Physics experiment demonstrating the repulsion between like electric charges, an elementary principle of electrostatics.
Step-by-step explanation:
The subject of the question is Physics, specifically related to static electricity and the behavior of materials when electric charges are involved. Here's an explanation of the procedure outlined:
- First, prepare two pieces of tape that are approximately 4 cm long. You create a handle on each piece by folding over 0.5 cm at one end so that the sticky sides adhere to each other.
- These pieces of tape are then attached side by side onto a nonmetallic surface. Once you peel them off, you're instructed to do so by holding the handles and letting the tape hang.
- If the tape bends and sticks to the hand, the suggestion is to use a shorter piece of tape or to shake it free of the hand.
- Finally, when you slowly bring the two pieces of tape together, they should repel each other because they have the same electrical charge after being separated from the same surface.
This is an example of how like charges repel, which is a basic principle of electrostatics in physics.
