Charge polarization is normally produced by ____________________. A) nuclear interactions.B) contact.C) induction.D) friction.E) electrostatic means.
To find the correct answer, we need to understand what charge polarization is and how it is produced. Charge polarization occurs when the charges within a neutral object are redistributed, resulting in one side of the object having a slight excess of positive charge and the other side having a slight excess of negative charge.
Now let's examine the options provided:
A) Nuclear interactions: Nuclear interactions involve the forces within the nucleus of an atom and are not directly related to charge polarization.
B) Contact: Contact alone does not produce charge polarization. It may allow the transfer of charges between objects, but it does not cause charge redistribution within a single object.
C) Induction: Induction is a process where a charged object can influence the distribution of charges within another object without direct contact. This is a possible mechanism for charge polarization.
D) Friction: Friction involves the relative motion between two objects, which can lead to charge transfer, but it does not necessarily cause charge polarization.
E) Electrostatic means: Electrostatic means refer to methods that involve the interaction of electric charges at rest. This includes processes like rubbing materials together or using an electric field. These methods can induce charge polarization.
Based on the provided options, the correct answer is E) electrostatic means, as it includes methods that directly induce charge polarization.
Therefore, the correct answer is E) electrostatic means.
