Physics 202 Thursday, January 21, 1999 Announcements: Physics Learning Resource Center 201 Osmond LAb Sunday: 8-10 pm Monday : 2:30-4:30 pm and 6-9 pm Tuesday: 2:30- 4:30 pm and 6- 10 pm Wednesday: 2:30 - 4:30 pm and 6- 10 pm Thursday: 6- 10 pm 202 Instructors will be available on Sunday and Monday Evenings! Lecture notes: Electric Fields Coulomb's law tells us what the force is acting between two specific charges If we are interested in knowing the of q 1 on a charge q 3 , at a different position, then we have to start from scratch. It is convenient to "map" out the "force per unit charge" due to charge q 1 , at all displacement from q 1 ; This is called the electric field due to q 1 . o To do this, we " imagine a test charge q o , that is positive and very small and calculate the electrostatic force between q 1 and q o as we move q o around. o q o is very small so that it does not distort what is going on near q 1 o F 1o = F = 1 q1qo 4 πε o r 2

    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.
