Question

The electric potential inside a conducting sphere is:

• A. Zero
• B. Increases from centre to the surface of the sphere.
• C. Decreases from centre to the surface of the sphere.
• D. Remains constant from centre to the surface of the sphere.

Hint:

In conductors, the electric field inside the material is zero, leading to a constant electric potential throughout the conductor.

Answer 1

The Correct Option is D

Step 1: Understanding the concept.
In a conducting sphere, the electric potential remains constant throughout the entire volume. The free charges in a conductor arrange themselves such that the electric field inside the conductor is zero, and as a result, the potential is uniform across the conducting material.
Step 2: Analyzing the options.
(1) Zero: This is incorrect. The electric field inside a conducting sphere is zero, but the potential is not zero; it is constant.
(2) Increases from centre to the surface of the sphere: This is incorrect. In a conductor, the electric potential does not increase or decrease within the material.
(3) Decreases from centre to the surface of the sphere: This is incorrect. The potential does not decrease in a conductor; it remains constant.
(4) Remains constant from centre to the surface of the sphere: Correct. The potential inside a conductor is uniform, and there is no change in the potential from the center to the surface of the sphere. Step 3: Conclusion.
The correct answer is (4) Remains constant from centre to the surface of the sphere, as the electric potential inside a conducting sphere is constant.
