\nThe correct option is B.
\n<\/section>\n
\nInside a conductor in electrostatic equilibrium, the electric field is zero. Electric field lines must be perpendicular to the surface of a conductor. In a parallel plate capacitor, the field is uniform between the plates in the absence of the sphere. When a conducting sphere is introduced, induced charges on its surface redistribute the field lines.
\n<\/section>\n
\nDiagram (b) shows the electric field lines entering and leaving the conducting spherical shell. Key features correctly depicted are:
\n1. The electric field lines are absent inside the conducting shell, indicating zero electric field within the conductor.
\n2. The electric field lines are perpendicular to the outer surface of the conducting shell at all points where they meet the surface.
\n3. The field lines are distorted by the presence of the conductor, originating from the positive plate, terminating on the induced negative charges on the near side of the sphere, originating again from the induced positive charges on the far side of the sphere, and finally terminating on the negative plate.
\nDiagrams (a) and (d) are incorrect as they show electric fields inside the conductor. Diagram (c) is incorrect as the field lines are not perpendicular to the conductor’s surface.
