It is said that unlike charges attract. You should have observed that after the sticky

side of a piece of scotch tape is pulled quickly off the smooth side of another piece of
tape the tapes attract each other. Perhaps each tape has the same type of charge and
the rule has been stated backwards. Why do you believe that the charges on the two
tapes are different? Note: It is not acceptable to answer “because unlike charges
attract and I observed the attraction.”

I thought I just answered this.

really where?

To determine why the charges on the two tapes are different, we can conduct a simple experiment.

First, take two pieces of scotch tape and stick them together, making sure the sticky sides are facing each other. Apply some pressure to ensure they are firmly stuck together.

Next, pull the two pieces apart by quickly peeling one away from the other. Observe what happens as you separate them.

If the pieces repel each other, it indicates that they have the same charge. This contradicts the initial observation where the tapes were observed to attract each other.

On the other hand, if the pieces attract each other as they are separated, it suggests that they have opposite charges. This aligns with the observation made initially.

Hence, based on the outcome of the experiment, we can conclude that the charges on the two tapes are likely different.
