The Average of the difference is obtained =0.952
Inorder to obtain the Time Period of the pendulum ,we have to multiply the obtained
average with two.
Therefore the time period of the pendulum = ( 0.952 *2)
= 1.904 seconds
Now using this value of time period we could easily determine the acceleration due to gravity
of the place.
The angle from which the pendulum is dropped =30 degrees
