A rod of length L on the y-axis has been non-uniformly charged with charge density given by 2 = ay where a has units of Cm and the total charge on the rod is Q. Answer the following questions as if you were being asked to find the electric field at the origin. Question 5 In general when we want to find the electric field from a continuous charge kdq distribution we start by setting up the general formula dE = . The first step is %3D to find dq for our particular situation. How would you write dq in terms of your chosen integration variable and other information given in the problem?
