Please answer questions 1 and 2 with an explanation. Consider Gauss's law: E = Qenc/epsilon0. where E = EA cos theta. Which of the following is always true? E must be the electric field due to the enclosed charge. If Qenc = 0, then E = 0 everywhere on the Gaussian surface. If the charge inside consists of a dipole, then E is zero. E is always parallel to the Gaussian surface. If a charge is placed outside the surface, then it cannot affect E on the surface. A point charge is placed at the center of a spherical Gaussian surface. The flux E is changed : if the sphere is replaced by a cube of the same volumn if the sphere is replaced by a cube of one-tenth the volumn if the point charge is moved off the center (but still inside the orignal sphere) if the point of charge is moved just outside the sphere if a second point charge is placed just outside the sphereExplanation / Answer
1.(A) and (C)..flux is generated by charged enclosed and flux is EAcos(theta) so E is the field due to charge enclosed.
In case of dipole charged enclosed is 0 so flux will be 0.
2. (A), (B) AND (D)
