Question

A conductor with an air core cavity inside, is charged to attain the surface charge density of \(\sigma\). If E is the magnitude of electric field and V is the potential, then inside the cavity

• A. \(E \neq 0\)
• B. \(V = 0\)
• C. \(E \neq 0\) and \(V = 0\)
• D. \(V \neq 0\) and \(E = 0\)
• E. \(\sigma = 0\) and \(E = 0\)

Hint:

For a charged conductor with a cavity, the electric field inside the cavity is zero in electrostatic equilibrium.
