Phys222 Lab Activity 3: Electric Fields for Continuous Charge Distributions Problem 1: A thin, non-conducting rod of length L carries a line charge 2(x) that varies with distance according to 2(x)=Ax? (in SI units) as shown in the figure. Note that A is a positive constant. Point P is located a distance d from the end of the rod as shown. a. What are the SI units of the constant A? b. Find the total charge Q on the rod. c. Find the electric field at point P due to the line charge. Note that you will not need the answer to part b to solve this. P X L d
