Refer to Exercise 14. Assume that the relative uncertainty in l is 3% and that the relative uncertainty in d is 2%. Find the relative uncertainty in R.

Step 1 of 2:

The resistance of a cylindrical conductor is given by R=, where l is the length, d is the diameter and k is the constant of proportionality. The relative uncertainty in l is 3%, and the relative uncertainty in k is 2%. We have to find the relative uncertainty in R.
