It is said that like charges repel. You should have observed that after the sticky side
of two pieces of scotch tape are pulled quickly off a table the tapes repel each other.
Perhaps each tape has a different type of charge and the rule has been stated
backwards. Why do you believe that the charges on the two tapes are like types of
charges? Note: It is not acceptable to answer “because like charges repel and I
observed the repulsion.”

  • physic -

    You have treated the two pieces of tape the same way, ripping them off the same table. (at least I assume the same table. If not then who knows)
