Question
The electric field associated with a uniformly charged hollow metallic sphere is the greatest at:
Correct Answer
Option B is the correct answer.
Detailed Explanation
Inside a hollow charged conductor the field is ZERO everywhere. Outside, the field behaves like that of a point charge at the centre (E = kQ/r2), which decreases as r grows. So the field is at its maximum right AT the outer surface.
Hint
Inside a hollow charged conductor the field is ZERO everywhere.
