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.

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

3. Protons are pulled out of the nuclei of atoms in the tape, and move onto your finger

Explanation:

The tap was positively charged earlier . Now it is neutral , that is why is is no longer attracted to the hand .

The first option is ruled out . When sodium ions moves onto the plate it will become more positively charged . So this reason does not appear to be plausible.

Third option too appears not plausible . Protons can not be pulled out of nucleus . Its binding energy is very high . So this reason is wrong.

Rest of the options appear plausible.
