6. Dr. Gilbert tried to hold a brass rod by hand and induce static electricity in it by friction. Why did he fail? a) Static electricity is induced only on insulators while brass is conducting b) The induced static charge flew through his hand and body to the ground c) The static charge was not produced at all d) It is not possible to induce static electricity by friction
Answer: b Explanation: The human body is a good conductor and hence the charge produced by friction flew through his body to the ground. We can tackle the problem simply by holding the brass rod with the help of some insulated holder.
