A caharged insulator can be discharged by 

The earth is such a large object that this transfer of electrons doesn't 

Electrical charges can move easily move through some substances such as 

Th diagram shows the location of charged atoms inside an insulated metal object when a - charged rod is brought near to it . The conduction electrons in the object moved from the left hand side of the object to the right hand side when the - charged rod was brought near the object 

A) why did the charges rod cause the conduction electrons to move to the other end 
B) why did the transfer of conduction electrons in the object make the one end positive and the other end negative 
C) in terms of electron transfer , explain why the insulated object would become - overall if the rod touched the object
