Hint: Charging by conductivity involves the contact of a charged object to a neutral object. Suppose that a charged Al plate is touched to a neutral metal sphere. The neutral metal sphere becomes charged because of the results of being contacted by the charged Al plate.
Complete step-by-step solution:
The charge on the rod is shared between the rod and also the sphere after they are a unit in touch with one another. However, on grounding the charge can flow to the earth, and also the charge on the sphere becomes zero.
Hence, Charging a metal sphere by contact using a positively charged rod, followed by grounding can result in Zero charge in a metal sphere.
Additional information:
You can charge a metal sphere without touching it by Connecting the sphere to the earth with a wire. The electrons can flow to the bottom whereas the positive charges at the close to finish can stay command there thanks to the attraction of the negative charges on the rod.
You can charge a metal sphere absolutely by induction by bringing a charged rod on the brink of an aluminous sphere placed on an insulated stand. Because the rod is brought on the brink of the sphere, the free electrons within the sphere move away because of repulsion and begin to spike up at the farther end. The close to finish becomes charged because of the deficit of electrons.
Note: Example of charging by contact:
During contact, or once being rubbed along, every material is charged. For instance, the hair and also the comb remain neutral. Once they are rubbed along, the atoms within the comb gain electrons, and also the atoms within the hair lose electrons.
