also would the slope of the trend-line represent the constant value k? I plotted both V to r and and also the magnitude of E to R and I get a slope of aprox... 8.77 which seems close to the k value of 8.99*10^9 ?

ok I reread your post and I thought you were telling me it should be linear. The question I am asked is...What I would expect "n" to be. Well I would expect it to be other than 1 because it is not a linear relationship ,the potential difference decreases with the first power of the distance...

r V 1 8.7 2 4.5 3 2.9 4 2.2 5 1.8 6 1.5 that is my data I got, and I made an excel. I added a trendline curved and got y=8.7715x^-2.011. The data was curved not linear? I am trying to associate the power function F(r)=Ar^n and determine n. Wouldn't n be the -2.011? Sorry your answer...

I am graphing Potential(Volts) y-axis vs distance (r) x axis. I am asked to fit a power function F(r)=Ar^n . Any ideas on how to do this? What is n supposed to represent?
