Question

A point charge q is placed at the center of a spherical Gaussian surface. The electric fix through the surface will change if:

a. the shape or the surface to a changed to a cube with the same volume as the original sphere.
b. the point charge is moved off center (but still inside the sphere) the point charge is moved to allocation just outside the sphere.
c. if a second point charge is placed just outside the sphere.
d. the radius of the surface is doubled.

Answer 1

. the point charge is moved off center (but still inside the sphere) the point charge is moved to allocation just outside the sphere.

Step-by-step explanation:

Because

Gaussian surface is given as

ϕ= qclose/E0

​So Q enclosed charge will be same if w the charge inside the Gaussian surface is moved, so flux will not change.
