Physics 2102, February 9, 2011. Activity 1: The figure shows two large parallel conducting plates that are 12 cm apart and have equal and opposite charge densities of their surfaces. The electrostatic force on an electron in between the plates is F = 3.9 x 10 -15 N. (i) Calculate the magnitude of the electric field between the plates: (ii) Calculate the potential difference between the plates. Which plate has higher potential? (iii) Calculate the change in electric potential energy of an electron that is moved from the negative to the positive plate Physics 2102, February 9, 2011.

Unformatted text preview: (ii) Calculate the potential difference between the plates. Which plate has higher potential? (iii) Calculate the change in electric potential energy of an electron that is moved from the negative to the positive plate Activity 2 The figure shows a family of parallel equipotential surfaces, and five paths along which an electron is moved from one surface to another. (a) What is the direction of the electric field associated with the surfaces? (b) For path (4), is the work done by the electric field positive or negative?

### What students are saying

• 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.
