Compute all parts of given question:
Question: A uniform charge density of 680 nC/m3 is distributed throughout a spherical volume of radius 6.00 cm. Consider a cubical Gaussian surface with its center at the center of the sphere.
Part A: What is the electric flux through this cubical surface if its edge length is 3.30 cm?
Part B: What is the electric flux through this cubical surface if its edge length is 18.0 cm?
So confused, please explain how you got the answers. Thanks.
