Which of the following statements are correct?
A. Inside a conductor, the electrostatic field is zero.
B. Electric field at the surface of a charged conductor does not depend on its surface charge density.
C. The interior of a charged conductor can have no excess charge in the static situation.
D. At the surface of a charged conductor, the electrostatic field must be normal to the surface at every point.
E. The electrostatic potential is zero everywhere inside a charged conductor.
Choose the correct answer from the options given below:

Asked in NEET 2026 · Electrostatics of conductors

• (1) A, C and D only
• (2) A, C and E only
• (3) C, D and E only
• (4) A, B and D only

Step-by-step solution

Why the other options are wrong

• (2) E is false: the potential inside a conductor is constant, equal to its surface value, and is not zero for a charged conductor.
• (3) E is false (the potential is constant, not zero), and A is left out although it is true.
• (4) B is false: the field just outside a conductor is σ/(ε₀), so it depends directly on the surface charge density.

Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
