Question

Which statement is true about a polarized object?

1. It gains electrons and becomes negatively charged
2. It gains protons and becomes positively charged.
3. The number of positive and negative charges can be the same.
4. It has to be a metal.
5. There is no change in the distribution of the charge in the object.

Answer 1

Answer: Option (3) is the correct answer.

Step-by-step explanation:

When an object is polarized then it means that if a negatively charged object is brought near a neutral atom then a positive charge will develop on the neutral object near the area of contact.

Whereas a negative charge will develop on the opposite side neutral object which is not in contact with the negatively charged object.

Hence, in a polarized object there are equal number of both positive and negative charges.

Thus, we can conclude that the statement number of positive and negative charges can be the same, is true about a polarized object.
