Compute all parts of following problem:
Problem: Consider a spherical closed surface, containing some protons. The total electric flux through the surface is 8x10-5 Nm2/C.
Part A: How many protons are inside the surface?
Part B: Where are the protons located? (Uniformly spread just inside the sphere, uniformly spread throughout the sphere, No way to tell from the information given, or at the center of the sphere)
I don't understand how to get the answer. Can you please help me with this problem?
