A sphere of radius contains a charge of , calculate the electric flux.

Tom is given an uncharged, solid sphere of radius . He then decides to charge all the material within a distance from the center uniformly. He gives that part of the sphere a total charge of . He then charges the rest of the material uniformly, giving that part of the sphere a total charge of . Besides the very center point of the sphere, at what distance from the center will there be no electric field?

An 8m by 8m square-base pyramid of height 4m is placed in a uniform vertical electric field of strength . What is the total electric flux that goes through the pyramid's four faces? (There is no charge inside the pyramid.)

You have a cube with a charge in the center. Each of the cube's sides is 12cm long. What is the flux through one of the faces of the cube?

Determine the electric field on the surface of a sphere of radius if are contained within.

Determine the electric flux on the surface of a ball with radius with a helium nucleus inside.

What is the flux from a charge inside of a sphere?

A sphere with a uniform volume charge distribution has a radius of 3m. What is the electric field at point C?

A spherical conductor has a radius of 0.04m. On the surface an amount of charge is evenly distributed with a surface charge density of . What is the strength of the electric field at the surface of this conductor?

Imagine a spherical conducting shell of inner radius and outer radius . If there exists a point charge of 5Q at a radius of less than (it sits within the void inside the conducting shell), and the total charge of the conducting shell is 3Q, what is the magnitude of the charge on the outer surface of the shell?
