6.) Sketch field lines for the following cases: a. The electric field lines around an isolated point charge 𝑞 > 0. b. The electric field pattern around two positive point charges of magnitude 1 𝜇 C placed close together. c. The electric field pattern around two negative point charges of -2 𝜇 C placed close together. d. The pattern around two point charges of +1 𝜇 C and -2 𝜇 C, placed close together. 7.) If the electric field strength in air exceeds 4.0 × 10 6 N/C, the air becomes a conductor. Using this fact, determine the maximum amount of charge that can be carried by a metal sphere 3.0 m in radius. Remember: points on the surface are considered outside a spherically symmetric charge distribution; the total charge may be considered to be located at the center of this sphere. 8.) The electric field everywhere on the surface of a charged sphere of radius 0.230 m has a magnitude of 575 N/C and points radially outward from the center of the sphere. a. What is the net charge on the sphere?

    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.
