Question

A glass marble is rubbed against a piece of silk. As a result the piece of fabric acquires extra electrons. What happens to the glass marble?

Check all that apply.
1) The marble has lost the same number of electrons acquired by the piece of silk.
2) The marble has acquired the same number of electrons acquired by the piece of silk.
3) The marble acquires a positive charge and repels the piece of silk.
4) The marble acquires a positive charge and attracts the piece of silk.
5) The marble acquires a negative charge and attracts the piece of silk.
6) The marble acquires a negative charge and repels the piece of silk.

Answer 1

The glass marble loses electrons to the silk and becomes positively charged, leading to attraction between the glass marble and the silk due to their opposite charges.

Step-by-step explanation:

When a glass marble is rubbed against a piece of silk, the process involves the transfer of electrons from one material to the other. In this case, the glass loses electrons to the silk. As a result, the correct statements regarding what happens to the glass marble are:

• The marble has lost the same number of electrons acquired by the piece of silk.
• The marble acquires a positive charge and attracts the piece of silk.

This happens because the glass becomes positively charged due to the loss of negatively charged electrons, and since the silk has gained those electrons, it becomes negatively charged. According to the principles of electrostatics, oppositely charged objects attract each other, leading to the attraction between the positively charged glass marble and the negatively charged silk.
