Three charges are enclosed in a cylindrical shell. What is the flux coming through the closed surface of the shell? Let q1 = 6 nC, q2 = 5 nC, q3 = -10 nC.

What is the electric field of a point charge of 57 nC at a point 10 cm away via Gauss' Law?

Challenging:

You have a solid sphere of charge Q and radius R.

The charge is uniformly distributed throughout the sphere. Which of the following is correct?

The electric field grows linearly with distance r from the center until r=R, then it falls like 1/r2.

The electric field is zero inside the sphere until r=R, then it falls like 1/r2.

The electric field falls like 1/r2 everywhere.

The electric field grows linearly everywhere.
