Answer the following questions:
(a) A magnetic field that varies in magnitude from point to point but has a constant direction (east to west) is set up in a chamber. A charged particle enters the chamber and travels undeflected along a straight path with constant speed. What can you say about the initial velocity of the particle?
(b) A charged particle enters an environment of a strong and non-uniform magnetic field varying from point to point both in magnitude and direction and comes out of it following a complicated trajectory. Would its final speed equal the initial speed if it suffered no collisions with the environment?
(c) An electron travelling west to east enters a chamber having a uniform electrostatic field in north to south direction. Specify the direction in which a uniform magnetic field should be setup to prevent the electron from deflecting from its straight line path.

Connected Sums (a) Explain in your own words (and pictures, if you'd like) why the connected sum of any surface with S^2 is topologically equivalent to the original surface. (b) At the end of Chapter 5 in The Shape of Space, we learned that every surface is a connected sum of either tori only or projective planes only. Based on this information, write each of the surfaces below as a connected sum of the correct number of only T^2s or only p^2s: T^2#p^2 = T^2#K^2 = p^2#S^2 = 2. This problem comes from #4 on page 80 of Topology without Tears. Find the closure in R of each set. You must give a reasonable justification for each answer but it doesn't need to be a formal proof. a) {1, 1/2, 1/3, 1/4, ..., 1/n, ...} b) the set Z of all integers c) the set P of all irrational numbers 3.

Your father is preparing the backyard for the installation of new sod. He has finished cleaning the ground of roots and rocks, has raked it to the correct contours, and now must pull a heavy roller, shown in (a) of the figure, over the ground several times to flatten and compact the dirt. He is tired after all of his work and asks you to do the rolling for him. He tells you that each section of the yard must be rolled over ten times with the roller. You are tired from your physics studying, but decide you can use your understanding of physics to make the job easier. You attach the roller to a spring as shown in (b) of the figure, with the other end attached to a post pounded into the ground. You then just pull the roller out once and let it oscillate over each part of the yard for ten rolls while you sit back and relax. Before beginning, you wonder how much time (in s) you will have to relax at each location before you have to move the post and roller to a new location. The mass of the roller is M = 368 kg, and the spring constant is k = 3,530 N/m. The flat, smooth ground supplies enough friction that the roller rolls instead of sliding, but the rolling friction is negligible. (Assume the roller is a solid cylinder.)
