PHYS 2002 : Spring 2015 Exam1
Document Summary
Name:______________________: please bubble in your version of the exam. You have version a: two charges q1 and q2 have equal magnitudes and are placed as shown in the figure below. The net electric field at point p is vertically downward. E: a point charge q = 0. 35 10-14 c is fixed at the origin near the surface of the earth as shown below. The y-axis is upward, and the x-axis is horizontal. At the midpoint on the line connecting the two charges, the electric field has a magnitude of 45 n/c. What is the magnitude of the charges: 7. 04 10-12 c, 1. 41 10-11 c, 2. 82 10-11 c, 3. 52 10-12 c, 9. 39 10-11 c, the electric field lines around three point charges are shown below. The charge in the middle, q2, has a value of -10 c. L2: an electron is released from rest in a uniform electric field. B: the capacitor in the rc circuit shown below is initially uncharged.
