Unformatted text preview: The energy of an electron at speed v in special relativity theory is E = mc 2 (1-v 2 /c 2 )-1 / 2 , where m is the electron mass, and c is the speed of light. The factor mc 2 is called the rest mass energy (the energy when v = 0). Find the rst three terms of the series expansion of E in v . What is the second term in the series? 6. (Problem 1.16.33, p. 43) If you are at the top of a tower of height h above the surface of the earth, show that the distance you can see along the surface of the earth is approximately s = 2 Rh , where R is the radius of the earth. (See the gure and the hints in the book.) Mathematical Physics, Fall, 2010 Problem Set I, Page 2 7. (Problem 4.12.16, p. 237) In kinetic theory, we have to evaluate integrals of the form I ( n ) = Z t n e-at 2 d t. Given that I (0) = p / 4 a , evaluate I for all integers n ....
