Clarke Web Assign Current Score: 23.5 out of 23.5 Due: Friday, September 12, 2008 12:30 PM EDT Description Reading: Sec. 15.1-15.3. Calculating the electric field due to charge distributed uniformly over an object. Read the assigned pages before trying the questions. The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. 1/1 points When calculating the electric field of an object with electric charge distributed approximately uniformly over its surface, what is the order in which you should do the following operations? Type the letters of the steps in order, separated by commas. (For example, you might type z,w,y,x if operation "z" were to be done first, etc.) a. Check the direction and units b. Write an expression for the electric field due to one point-like piece of the object c. Divide up the object into small pieces of a shape whose field is known d. Sum the vector contributions of all the pieces Order of steps: c,b,d,a c,b,d,a 2. 8.5/8.5 points A plastic rod 1.4 m long is rubbed all over with wool, and acquires a charge of -4e-08 coulombs.
