Physics 523 Midterm Exam, Fall 2011 Thursday, October 27, 3:00-4:20pm This exam consists of 3 problems (with multiple parts) on 2 pages, worth a total of 100 pts. Do all problems, answered in the exam booklet provided, and clearly show all your work. This is a closed-book exam. Non-programmable calculators may be used (though should not be necessary). Remember to write your name in the exam booklet, and write and sign the pledge : I pledge my honor that I have not violated the Honor Code during this examination. Problem 1. [30 pts total] Consider a point charge in Maxwell’s theory described by 4-potential A μ with components ( A t , A x , A y , A z ) = ( q/r, 0 , 0 , 0) in Minkowski spacetime ds 2 = dt 2 + dx 2 + dy 2 + dz 2 , where r = radicalbig x 2 + y 2 + z 2 and q is a constant. Recall: F μν = A μ,ν A ν,μ E α ( n ) = F αβ n β B α ( n ) = 1 2 ǫ αβγδ F γδ n β n α n α = 1 (a) [15 pts] What are the components of the electric and magnetic 4-vectors seen by an observer n α at rest with respect to the ( t, x, y, z ) coordinate system?

    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.
