Document Summary
Summer ii 2010: answer the indicated number of questions in each section below, all problems have equal weight. In a scattering experiment to reveal the atomic-scale structure of a material, electrons are accelerated through a potential difference of v = 500 kv. A muon is formed from a cosmic ray shower in the upper atmosphere at an altitude of 1 km. The kinetic energy of an electron is increased by a factor of two. Electric forces, elds, and energy (choose 3 of 4) The two gures below show small sections of two different possible surfaces of a nacl surface. In the left arrangement, the nacl(100) surface, charges of +e and e are arranged on a square lattice as shown. In the right arrangement, the nacl(110) surface, the same charges are arranged in a rectangular lattice. Which is more stable? a a a a 2. A conducting spherical shell of radius r surrounds a point charge +q.
