Answer:
A
Explanation:
A)
INCORRECT
No, Gauss’s Law can not be derived from Coulomb’s Law alone. Since, Coulomb’s Law provides electric field produced by a single point charge. Therefore, it is important to assume principle of super position along with Coulomb’s law to get the field due to all charges. So, Gauss’s Law can be proved by the help of both Super Position Principle and Coulomb’s law.
B)
CORRECT
Yes, Gauss’ law states that the net number of lines crossing any closed surface in an outward direction is proportional to the net charge enclosed within the surface.
C)
CORRECT
Yes, Coulomb’s law can be derived from Gauss’ law and symmetry.
D)
CORRECT
Yes, Gauss’s Law applies to a closed surface of any shape.
E)
CORRECT
Yes, if a closed surface encloses no charge, the electric field is zero everywhere on the surface.
