1. For this lab we will linearize the data to obtain informationfrom the data.
2. Part A: We seek to verify that the electric field doesindeed go as 1/r2.
   1. This is accomplished by plotting the electric field data versusr-2 not vs. r alone.
   2. After you have fit the data you will need to estimate the errorin the slope of the line.
   3. One you have estimated the error in the slope of the linecompare this value to the expected valuekcq using a numberline.
   4. Compare the values from (d) using a percent error.
   5. Discuss the agreement or disagreement of your data.
   6. Discuss sources of error in your measurements or setup (noteyou may need to be imaginative here).
