A point charge is placed inside a cavity within a solid isolated conducting sphere. Consider points , and as shown in the figure, where the magnitudes of the electric fields are , , , respectively. The points and are at the same distance from the center of the solid sphere. The correct option is :
Figure: a solid isolated conducting sphere with a small off-centre cavity containing the point charge . Point is inside the cavity near ; and are outside the sphere on opposite sides, at equal distances from its centre.
