Electric shielding within a conductor is a consequence ofA. both the attraction and repelling nature of electricity.
B. cancellation of electric field lines.
C. all of the above
D. the balancing of opposing forces.
E. none of the above
Final answer:Electric shielding within a conductor occurs due to the redistribution of free charges that move in response to an electric field, resulting in a cancellation of the electric field within the conductor. The correct answer to the student’s question is option C, which indicates both the attraction and repelling nature of electricity, along with the cancellation of electric field lines, cause this effect.Explanation:Electric shielding within a conductor is a fascinating topic in physics, grounding on the fundamental principles of electrostatics. When a conductor is placed in an electric field, free charges within the conductor start to move. This reorganization of charge is due to the force exerted on these charges by the electric field. Positive charges in a conductor will move towards the negative end of the applied electric field, while negative charges will move towards the positive end. This redistribution of charge continues until the internal electric field is canceled out.The resulting effect is that the conductor acts as a shield, either preventing external electric fields from affecting the interior (similar to a Faraday cage), or preventing internal electric fields from influencing the external environment. The critical point here is that the redistribution of charges within the conductor creates an opposite electric field that cancels the original electric field, leading to zero net electric field inside the conductor. The electrostatic force and their ability to move freely within the conductor explains why charges will always redistribute until this balance is achieved.Given the information provided, the correct answer can be elucidated by understanding that the attraction and repelling nature of electricity causes the charges to rearrange until the electric field is canceled, reflecting both contributions to the phenomenon. Thus, the concept of electric shielding is best encapsulated by the option that alludes to both the attracting and repelling nature of electric charges and the resultant cancellation of electric field lines to explain the shielding effect.Therefore, the correct answer to the student's question is C. all of the above, indicating that electric shielding within a conductor is a consequence of both the attraction and repelling nature of electricity and the cancellation of electric field lines....
