Explanation:
The correct answer is option B, which states that the electric field is not zero anywhere on the sphere.
Reasoning:
To understand why this is the correct answer, let's analyze the situation step by step.
1. Electric Dipole at the Center:
When an electric dipole is placed at the center of a conducting sphere, the electric dipole moment is aligned with the electric field lines. The positive charge of the dipole is directed towards one end, and the negative charge is directed towards the other end.
2. Electric Field due to the Dipole:
The electric field due to an electric dipole decreases with distance from the dipole. At the center of the dipole, the electric field is maximum, and it decreases as we move away from the dipole.
3. Electric Field inside a Conductor:
Inside a conductor, the electric field is always zero. This is because the free charges within the conductor rearrange themselves in such a way that the net electric field inside the conductor becomes zero.
4. Electric Field Outside the Conductor:
Outside the conductor, the electric field can exist. The presence of the conducting sphere does not affect the electric field due to the dipole. The electric field lines due to the dipole will pass through the conducting sphere.
Conclusion:
Based on the above reasoning, we can conclude that the electric field is not zero anywhere on the sphere. The electric field lines due to the dipole will pass through the conducting sphere, and the electric field will be present outside the conductor. Therefore, option B is the correct answer.
