Electromagnetic Field Theory - GATE practice papers - Electronics & Communication for Q. 535
Q. Which among the below given statements are correct in accordance to the properties of a conductor?
A. The static electric field intensity at the surface of conductor is directed parallel to the surface.
B. The static electric field intensity at the surface of conductor is directed perpendicular to the surface.
(Marks : 02)- Published on 19 Oct 15a. Only A is correct
b. Only B is correct
c. Both A & B are correct
d. Both A & B are incorrect
ANSWER: Only B is correct
Conductor develops an equal potential throughout the surface and the static electric field intensity within the inner portion of a conductor is zero. Thus, the properties of a conductor implies that the static electric field intensity over the surface of a conductor is directed equally and normal (perpendicular) to the surface.
