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. view available hint(s) check all that apply. the marble has lost the same number of electrons acquired by the piece of silk. the marble has acquired the same number of electrons acquired by the piece of silk. the marble acquires a positive charge and repels the piece of silk. the marble acquires a positive charge and attracts the piece of silk. the marble acquires a negative charge and attracts the piece of silk. the marble acquires a negative charge and repels the piece of silk. submit

Answer 1

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.

Step-by-step explanation:

As we know that charging of an object is related to transfer of electrons. When an object becomes negatively charged then it shows that it will get excess of electrons while for positively charged it will lose some electrons.

So here we know that glass is rubbed with silk cloth so here silk cloth will gain some electrons and gets negative charge while glass will lose same electrons and becomes positively charged.

So here due to equal and opposite charge on silk and glass they both will attract each other.

So here correct answers will be

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.

Answer 2

So when a glass marble is rubbed against a silk cloth, the silk cloth acquires some electron from glass marble. So the from the given option two statements apply to the situation, the marble has lost the same number of electrons acquired by the piece of silk and the marble acquires a positive charge and attracts the piece of silk.
