3/17/06 Exam 2 Name____________________________________Section______________ 1. Two charges + q and - q are located along the y -axis at y = +a and y = –a , respectively, as shown. a. On the diagram, draw and label a vector r E + that represents the electric field due to + q at the point (+ 3 a , 0), as indicated by the tiny circle. Draw and label a vector r E " that represents the electric field due to – q at that same point. Be sure to clearly show their directions and relative magnitudes. (2 points) b. Find the magnitude and direction of the electric field at the point (+ 3 a , 0) in terms of any or all of the following: q , a , and fundamental physical and mathematical constants. (12 points) c. Now a charge q 0 is placed at the point (+ 3 a , 0). Find the magnitude and direction of the electric force on q 0 in terms of any or all of the following: q , q 0 , a , and fundamental physical and mathematical constants. (2 points)
