General Physics II Homework 5 Worked Examples Giancoli: 17.30, 17.40, 17.49, 17.54, 17.66, 17.75 30. We assume that and are equal in magnitude, and that each makes a angle with . The magnitude of is also given by , where is the charge on the hydrogen atom, and is the distance between the H and the O. This is about 0.32 times the charge on an electron. 40. After the first capacitor is disconnected from the battery, the total charge must remain constant. The voltage across each capacitor must be the same when they are connected together, since each capacitor plate is connected to a corresponding plate on the other capacitor by a constant-potential connecting wire. Use the total charge and the final potential difference to find the value of the second capacitor. 49. ( a )Use Eq. 17-8 to estimate the capacitance. ( b )Use Eq. 17-7 to estimate the charge on each plate. ( c ) Use Eq. 17-4b to estimate the (assumed uniform) electric field between the plates. The actual location of the field measurement is not critical in this approximation.

    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.
