You must show ALL work in a clear and organized manner in order to receive full credit. Insufficient work or incomplete explanations will result in a loss of points. 2. Cheating will be dealt with severely. Keep your eyes on your own paper, and do not attempt to talk or communicate to any student around you. Students who are involved in any kind of cheating will receive a ZERO on this test, and will be referred to the Dean of Students for disciplinary action. 3. Except for a simple numerical mistake in adding points, any appeals regarding how this exam was graded must be submitted in writing (return the exam also) within 3 class meetings after the test was handed back. Test #2 Raw Score: ____ / 60 Test #2 Grade: _____ / 100 1. (10 pts) Fill in the blanks for the following sentences. If a charged particle is placed in an electric field it will experience a ___________, and this will cause the charged particle to _________________ . While accelerating, the charged particle will move through a _________________, which means that the force is doing ________ on the charged particle. If the force and displacement are in the same direction, the work done by the electric field is ___________ . Positive work causes the kinetic energy of the charged particle to ________________ and the potential energy to _______________. Electric potential is defined as the potential energy per unit ___________. Only ____________ in electric potential are important. When calculating the change in potential between two locations the ________ does not matter. If a charged particle is moved through a potential difference, the particle will experience a change in ______________ _________. Write this sentence as an equation. If a potential difference exists between two locations, than an _______________ ________ must also exist in that region, and this electric field points in the direction of __________________ ______________ ______________ . Write this sentence as an equation. Page 2 Test #2 (chapters 29, 30, 31, 32) PHYS-224 Dr. Russell (Summer 2008) 2. (10 pts) A proton moves from point a to point b in the vicinity of a point charge !
