Homework Statement
I have a second problem I need assistance with but I'll put it in its own thread.
Used centripetal apparatus to run trials with varying radii but constant mass and calibration weight (mg). I have already plotted T^2 vs r^2 and got a slope of 16.5 from the best fit. I now have to solve the equation for T^2 and then use it to determine the centripetal force. I know the slope is T^2/r, but I don't know how to use that.
Mass M = .138kg
Calibration weight= .050 kg so measured force is .490.
slope = 16.5
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 centripetal force from the slope.
T^2=(5.92M)/F
T^2*F= 5.92M
(T^2*.490)/5.92=M
.490/5.92=M/T^2
2.92*T^2=M
New try.
T^2=4pi^2rM/F
T^2F= 4pi^2rM
(T^2F)/r=4pi^2M
Do I need to get the slope onto one side of the equation?
