Physics Assignment HELP!!

[Proud.Hijaabi]

I don't know how to make this linear. I've tried 1/d and 1/d(squared). Does anyone have any ideas on how I can make this linear?

Seperation (cm) Force (N x 10^-9)
39 5.07
49 3.17
60 2.10
70 1.45
81 1.20
91 0.90

If you cannot, that is fine, but if you can that would be a lot of help! THhank you!

sorry but the first column has only 2 digits and the second column is another set of numbers ( I dont know what happened)

 

[CosmicPathos]

no idea what the question is.

take log of second column, then plot. I think that will give a linear line.

d^(-2), is a good approximation and force often acts that way according to distance.

THank you everybody, I realized I was doing something wrong thank you for your help though!
