You run your finger along the slick side of a positively charged tape, and then observe that the tape is no longer attracted to your hand. Which of the following are not plausible explanations for this observation?Check all that apply.
1. Sodium ions (Na⁺) from the salt water on your skin move onto the tape, leaving the tape with a zero (or very small) net charge.
2. Chloride ions (Cl⁻) from the salt water on your skin move onto the tape, leaving the tape with a zero (or very small) net charge.
3. Protons are pulled out of the nuclei of atoms in the tape, and move onto your finger.
4. Electrons from the mobile electron sea in your hand move onto the tape, leaving the tape with a zero (or very small) net charge.
