A) A spherical Gaussian surface surrounds a point charge q. Describe what happens to the total flux through the surface if
1) the charge is tripled,
2) the radius of the sphere is doubled,
3) the surface is changed to a cube, and
4) the charge is moved to another location inside the surface.
B) Suppose a point charge is located at the center of a spherical surface. The electric field at the surface of the sphere and the total flux through the sphere are determined. Now the radius of the sphere is halved. What happens to the flux through the sphere and the magnitude of the electric field at the surface of the sphere?
C) In which of the following contexts can Gauss's law not be readily applied to find the electric field? (a) near a long, uniformly charged wire (b) above a large, uniformly charged plane (c) inside a uniformly charged ball (d) outside a uniformly charged sphere (e) Gauss's law can be readily applied to find the electric field in all these contexts.
