An apparatus similar to the one used in this experiment is used to run the same experiment on the surface of a hypothetical planet. Kaleidagraph is used to make a plot of τ vs. L1/2, where τ is the period of oscillation and L is the length of the string. The slope from the equation of the best fit line is found to be:
slope=2.722 ± 0.041 s/m1/2.
What is the acceleration due to gravity on the surface of this hypothetical planet?
What is the uncertainty in the acceleration due to gravity found above?
