Question

When a body is charged by induction, then the body
A. becomes neutral
B. does not lose any charge
C. loses whole of the charge on it
D. loses part of the charge on it

Answer 1

Hint:Each body possesses electric charge. There are two types of electric charges, one is positive charge and the other is negative charge. Positive charge is known as proton and negative charge is electron. The magnitude of the charge is the same on both the proton and the electron but the polarity is different. Also, not all the bodies can be charged.

Complete answer:
In case of induction to charge a body, we bring a charged body near it but the two bodies do not touch each other. When this happens, polarization takes place and suppose if the brought body is positively charged then the end near the positively charged body negative charge comes and the positive charge gets on the other side. The part of the body nearer to the source charge gets induced charges, opposite in nature to the source charge while the other part gets those of similar nature. Thus, no loss of charge.

So, the correct option is B.

Additional information:
Induction charging is a charging method that charges an object without actually touching the object to any other charged object. The charging by induction process is where the charged particle is held near an uncharged conductive material that is grounded on a neutrally charged material. The charge flows between two objects and the uncharged conductive material develops a charge with opposite polarity.

Note:Most of the objects are electrically neutral. But it does not mean that there are no charges present in it. It means that there are an equal number of positive and negative charges in it. In order to charge an object, one has to alter the balance and in order to do that, there are three ways to do: friction, conduction and induction.
