Similarly one may ask, which of the following Cannot be charged by friction if held by hand?
Copper rod cannot be charged easily by friction because it is a conductor. Only non-conducting materials can be charged easily by friction.
Also Know, how can you detect whether a body is charged or not? An electroscope is used to detect that a body is charged or not. It works on the principle that like charges repel while unlike charges attract each other. When the metal strips repel each other proves that the body is charged because repulsion is the sure test to detect that a body is charged or not.
Also to know, can a charged glass rod attract a charged plastic straw?
A charged glass rod has positive charges on its surface while a charged plastic straw has negative charges on its surface. Since unlike charges attract each other, a charged glass rod attracts a charged plastic straw. Hence, lightning conductors protect a building from lightning.
Why charged body loses its charge if we touch it with our hand?
When we touch a charged object, our body works as a natural conductor and automatically conducts its charges to the earth. That is why of contacted by hand, a charged body loses its charge, as the hand works as the medium of transmitting the charge in the earth with our hand.
