Q

when an object becomes charged by rubbing where do the electric charges come from

A

the procces of rubbing leads to a redistribution of charge

Q

a teacher rubs a felt cloth against a glass rod. what will happen after this situation

A

the two objects will be attracted to each other.becuase one turned postive and the other negative charged . opposites attract

Q

a hand touches a conducting electroscope what happens in terms of charges

A

the negative charges in the electroscope feel a repulsive force form the negatively charged outside object and an attractive force from the hand. these excess electrons transfer to the hand which acts as a conductive path to the ground.

Q

when a charged object touches an initially neutral object which then undergoes polarization. after that, it is exposed to a source that grounds the material. the final product is a charged object with the charge of the object that was brought near to it.

A

charging by induction
