Question
Transcribed Image Text:Plot graphs for the data in Table 2 and determine the minimum and maximum slopes. Substitute
the average slope in the equations in the tables and secure values of g. From the minimum and
maximum slopes calculate the minimum and maximum values for g and assign the difference
divided by 2 as the error.
bo
In Table 2 gaverage + (gmaximum - gminimum)/2
Compare this with the accepted value of g in each case by completing the information at the bottom
of each table.

Assume we have errors of 0.1 cm in the values of T and L. Compute the influence of each of these
errors on the experimental values of g in Table 1. (Adjust the values of T and L by 0.1cm to get
the biggest or smallest values.)
