Question

Here is a variant of “charging by induction.” Place two uncharged metal objects so as to touch each other, one behind the other. Call them front object and back object. While you hold a charged comb in front of the front object, your partner moves away the back object (handling it through an insulator so as not to discharge it). Now you move the comb away. Explain this process. Use only labeled diagrams in your explanation (no prose!).

Short answer

The diagram has been drawn below the front sphere will have electron deficiency and the other one will have a greater number of electrons.

Step-by-step solution

Significance of the charging by induction for the objects

Induction charging is referred to as a method that is used for charging a particular object without keeping in contact with any other charged object to the uncharged object.

The induction charging is beneficial for explaining the process.

Explanation of the process by the induction charging

Consider three figures for the process of induction charging where the charge redistribution happens in the three figures.

The diagram of the process has been drawn below:

In figure (1), the neutral spheres are shown. The electrons are travelling from the front to the back sphere by point of contact as shown in figure (2). If the spheres are separated, then the electrons will not return to the front sphere as shown in figure (3). Hence, the front sphere will have electron deficiency and the other one will have a greater number of electrons.

Thus, the diagram has been drawn with the front sphere having electron deficiency and the other one will have a greater number of electrons.
