Document Summary

Problems will be graded on reasoning and intermediate steps as well as on the final answer. Be sure to include units and direction of vectors when needed. Constants: c 3 x 108 m/s, k 9x109 nm2/c2, me=9. 1x10-31 kg = 0. 51 mev/c2, h= 6. 62 x 10-34 m2 kg/s, hc = 197. 3ev " nm , e = 1. 6 x 10-19 c mproton = 1. 67 x 10-27 kg, Total: multiple choice questions and short problems. Explain your reasoning that leads to the final answer: circle the correct answer below. And in b it is i=2/3*(v/r) so it is larger and a is dimmer than b. Using gauss" law: r < a e =0 in the shell ab e = kq/r^2. C)a parallel plate capacitor of area a and distance between the plates d is charged with charge q and insulated. And the variation of the potential energy is. Answer true or false for the following statements and explain why.
