Packard Name: SID Discussion Section # Work all problems. Do not perform any numerical calculation until you have a final boxed algebraic answer. In order to obtain maximum partial credit show all your work clearly. Cross out work that you do not wanted graded. Work the easiest problem first and then move on to harder ones. If you don’t understand what is being asked in a problem, ask the proctor for clarification. All problems are weighted equally. Good luck. 1. 2. 3. 4. Total Integral table: i - “a -x Constants: c=3x10%m/s, h=6.6x10js, e=1.6x10°C, m,=9x10°kg, G=6.67x10"'Nm?/kg? 1. A photon of energy 2x10°eV collides with a free electron, initially at rest. The photon emerges at an angle of 60°.A) At what angle will the electron emerge? B) What is the emerging electron’s kinetic energy?
