(c) When the spheres are close to each other, the excess negative charges on each sphere repel, as shown in Fig- ure 17.3c. Figure 17.3 Reflect: We will learn later in the chapter that the excess charge on a conductor is on the surface of the conductor. 17.4. Set Up: Unlike charges attract and in a conductor the excess charge is free to move. Solve: Negative charge in the earth is pulled to the surface beneath the charged cloud, as sketched in Figure 17.4. Figure 17.4 17.5. Set Up: The charge of one electron is Solve: (a) (b) 17.6. Set Up: The total charge is the number if ions times the charge of each. Solve: 17.7. Set Up: Charge conservation requires that the total charge Q of the reactants equals the total charge of the products. and has charge and each have charge Solve: (a) reactants: products Could not occur. (b) reactants: products Could occur. (c) reactants: products Could not occur. (d) reactants: products Could not occur. (e) reactants: products Could occur.

    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.
