1. The problem statement, all variables and given/known data A distance R is measured to be 3.400±0.003m. What is the relative uncertainty in R? 9×10-4 What is the relative uncertainty in R^-2? 2. Relevant equations 3. The attempt at a solution Relative uncertainty of R is 0.003/3.4=8.8e-4 Relative uncertainty of R^-2= -2(8.8e-4)=-1.76e-3? How do you calculate relative uncertainty with a negative exponent?
