I did this experiment with various values for (d), which is the height from the top of the string to the stop. The length of the string was 0.7m. Since i used 6 differnt values for (d) i got 6 readings.
why i stated all this is because i have to find g from the following expression
T = \frac{-\pi^2}{g} (\frac{d}{T}) + 2\Pi \sqrt{\frac {l}{g}}
I have tried lots of variations but i just can't find anything close to 9.8m/s^2.
what i did was i tried a single set of results like:
d = 0.5m
T = 1.31
thus d/T = 0.38
and l = 0.7m
could someone use the same and tell me what their result for g was, please.
