Homework Statement
I have another problem with a similar thread title but they are not the same, I'd love help with either or both.
Ran trials with varying mass, but radius and centripetal force as constants. Must find experimental radius from the best fit slope. I have already finished the graph and found the slope. I know the slop is T^2/M, but I don't know how to use that.
Radius = .15
calibration weight 0.050
slope = 5.07
Homework Equations
F=4pi^2rM/T^2
The Attempt at a Solution
T^2=(4pi^2rM)/F I've tried rearranging it many ways but I can't figure out how to use this to determine radius from the slope.
4pi^2*.15M=1/F/T^2
5.92M= 1/F/T^2F*T^2=4pi^2rM
(F*T^2)M=4pi^2r
((F*T^2)M)/4pi^2=r
(.490*T^2)M) /39.47=r
Will subbing in mg for F do anything useful?
