Electric field at any point inside a hollow charged conductor is
A{'text': 'kq/r²', 'label': 'A'}
B{'text': 'zero', 'label': 'B'}
C{'text': 'the same as at the surface', 'label': 'C'}
D{'text': 'directed radially inward', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': 'zero', 'label': 'B'}
1. NCERT result 1 of §2.9: inside a conductor in electrostatics, E = 0.
2. Any free charges have already redistributed so the interior field is null.
3. (A) would be true for a point charge in vacuum, not for the interior of a conductor.
