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.”

Please explain in detail
