Surface Charge Density and Electric Field of a Charged Conductor

Assertion: Sharper is the curvature of spot on a charged body lesser will be the surface charge density at that point. Reason: Electric field is non-zero inside a charged conductor.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Both Assertion and Reason are true but Reason is not correct explanation of Assertion.
Assertion is true but Reason is false.
Assertion and Reason are false.

Solution:

Surface charge density is directly proportional to curvature \(\sigma \propto 1/R\). Inside a conductor, the electric field is zero. Hence, both statements are false.
