हिन्दीA point charge Q is placed inside a cavity within a solid isolated conducting sphere. Consider points A, B and C as shown in the figure, where the magnitudes of the electric fields are E_A, E_B and E_C, respectively. The points B and C are at the same distance from the center of the solid sphere. The correct option is :
Correct answer · Option 1
\( E_A = 0,\ E_B = E_C \)
Explanation
Inside the conductor (point A), electric field is zero (E_A = 0). Outside the conducting sphere, the field at B and C due to total charge on the outer surface is identical since B and C are equidistant from the center, so E_B = E_C.
