alleryElectric field inside a spherical cavity in a uniformly charged conductor is:
AMaximum
BEqual to outside
CZero
DVariable
Answer & Solution
Correct answer: C. Zero
In electrostatic equilibrium, any cavity inside a conductor has zero electric field — even if charge surrounds it.
By Gauss's law, no charge inside the conductor's bulk
→ no field in the cavity.
(Faraday cage principle.)
