2 Multiple Choice (2 pts. each) 1) Two point charges are fixed in space: a particle of charge q q 8 1 = located at the origin and a particle of charge q q 2 2 - = located at x = L . At what point (other than infinitely far away) can a proton be placed so that it is in equilibrium? L 1 q 0 + 2 q x A) L x 3 - = , B) L x 2 3 - = , C) L x 3 2 = , D) L x 2 = . Answer__________ 2) Two identical conducting spheres A and B are separated by a (center-to-center) distance d that is large compared to the spheres. Sphere A has a positive charge of +Q, and sphere B is electrically neutral. Initially, there is no electrostatic force between the spheres. (Assume that there is no induced charge on the spheres because of the large separation). The spheres are connected for a moment by a thin conducting wire. What is the magnitude of the electrostatic force between the spheres after the wire is removed? A) 2 d Q k ; B) 2 2 d Q k ; C) 2 4 d Q k ; D) 2 16 d Q k . Answer__________

### 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.
