Electric Flux & Gauss's Law
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:
Show answer and solution
Answer: (c)
- A: True, inside a conductor.
- B: False, depends on .
- C: True, excess charge lies only on the surface.
- D: True, the field is normal to the surface at every point.
- E: False, the potential inside is constant (equal to the surface value), not zero.
- So the answer is (c) A, C and D only.
