Answer» Solution :Metals are conductors and glass is an insulator. If a person TOUCHES a charged body, the body LOSES to charge to ground and this is known as 'earthing'. In case of a metallic rod, charges are free to move through the body, and even if the person touches the body at 'A', the body loses its WHOLE charge to the earth. Where as in case of glass rod,only the charge that is in CONTACT with the person gets earthed and the remaining charge on 'CD' will REMAIN as it is.
