In the video, the students discussed with the professor how objects can become charged through contact interactions at the microscopic level. Which of the following could possibly happen when two neutral objects are rubbed together? There may be more than one possibility. (Select all that apply.)
a) There might not be any changes to the chemical bonds between atoms, and the two objects remain neutral after contact.
b) Rubbing imparts energy to the two objects, allowing them to create excess electrons and thereby allowing both to have a net negative charge after contact.
c) Chemical bonds can break in such a way that atoms in the objects can gain or lose electrons. One object can gain electrons overall, with the electrons coming from the other object. The two objects thereby end up with opposite net charges.
d) Friction between the two objects can destroy electrons in them, allowing both to have a net positive charge after contact.
By rubbing two neutral objects, chemical bonds will break in such a way that atoms can either gain or lose electrons. That is one object can gain electrons and other may lose electron. Two objects may end up with opposite net charges. Such as if a negative charged object rubs a neutral ,then neutral object will acquire positive charge. If a positive charged object rubs a neutral object by induction, then neutral object will acquire a negative charge. So as per options, c suits as answer.
Hope u got it
