Question
on a microscopic level, when an object is charged by rubbing. For Instance, what happens when a plastic pipe is rubbed with a cloth? 2 Two pith balls hang side by side close to each other without touching as shown in the igure below. They are both neutal to begin wth a. A plastic rod is rubbed with wool. Describe as negative, positive or neutral the total (net) charge of a system consisting of the rod and the cloth. Explain your reasoning b A suenlhsphere A bwenhy with the rod and then removes E Then he brings the rod closeto phere A bu dots naf tuch k na it. What will happen to A? Explain your reasoning C. What is the charge state of the system consisting of the rod and wool now? Explain your reasoning d. Now sphere B is brought very close to A but does not touch it. What wial happen to the spheres? Explain your reasoning e. Now the student touches sphere B with the same charged rod as above. What will happen to spheres A and B afterwards? Again, the spheres are close to each other but do not touch. Explain your reasoning f What is the charge state of the system consisting of the rod and both spheres? Explain your reasoning g Sphere B is now discharged. Then t is touched by a glass rod that was rubbed with silk. Now both spheres are brought close to each other What will happen to the spheres now? Explain your reasoning h. Both spheres are now moved a bit further apart. What will happen to them now? Explain your reasoning Start DateExplanation / Answer
when object is rubbed , due to friction , heat is generated and this heat breaks the bonds between atoms inside the neutral molecule.hence the molcule divides in positive and negative ions the transfer of electron to an ion makes it negatively charge due to excess of electrons while the transfer of electrons from an ion makes it positive due to deficiency of electrons.
when plastic pipe is rubbed with cloth , the the platic pipe becomes negatively charged after getting some electron from cloth and cloth becomes positivly charged ,
