solution to quiz1.tex 1. 1 Φ E = 3 . 0 × 10 6 Nm 2 /C 2 Φ E = 0 hint: Φ E E A cos θ , where θ is the angle between the direction of the field and the direction normal to the area. 2. stay the same hint: From Gauß’s theorem, the number of field lines through a closed surface is proportional the enclosed charge, which is a constant for this problem. 3. 2 . 25 × 10 - 9 N/m hint: According to Hook’s law, | F | = κx where κ is the spring constant. On the other hand, F is just the Coulomb attraction between the two charges. 4. 5 × 10 5 N hint: The number of charges is n = 1 gram/m p where m p is the proton mass, so the resulting Coulomb force is F = k ( ne ) 2 / (2 R E ) 2 . 5. E a = kq/r 2 a , E b = 0, E c = kq/r 2 c hint: There will be a total charge of

    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.
