Problem Set 2 1. The colored regions in the figure represent four three dimensional Gaussian surfaces A through D. The regions may also contain three charged particles, with ݍ ൌ ൅5.00nC , ݍ ൌ െ5.00nC and ݍ ൌ ൅8.00nC , that are nearby as shown. What is the electric flux through each of the four surfaces? 2. A pyramid has a square base with an area of 4.00m and a height of 3.50m . Its walls are four isosceles triangles. The pyramid is in a uniform electric field of 655N/C pointing downward. a) What is the electric flux through the square base? b) What is the electric flux through one of the four triangular walls? c) What is the electric flux through all four triangular walls combined? 3. A 6.20ߤC point charge is at the center of a cube with sides of length 0.500m . a) What is the electric flux through one of the six faces of the cube? b) How would your answer to part (a) change if the sides were 0.250m long? Explain.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
