A particle with charge q is located inside a cubical gaussian surface. No other charges are nearby. If the particle is at the center of the cube, what is the flux through each one of the faces of the cube?
1. 0
2. q/20
3. q/6 0
4. q/8 0
5. depends on the size of the cube
[Ques. 2] Why did you use the average value for k from Data Table 7.1 rather than one of the individual trial values?
[Ques. 3] In which of the following contexts can Gausss law not be readily applied to find the electric field?

[Ques. 5] A uniform electric field of 1.00 N/C is set up by a uniform distribution of charge in the xy plane. What is the electric field inside a metal ball placed 0.500 m above the xy plane?
