Question

Suppose the period of a pendulum is measured to be 0.6 +/- 0.035 s and we want to find T2 and it's error.

Finding T2 is easy, it is: [Num] [Units]

To find the error in T2 we first need to find the relative error in T.

Recall equation 1.2, The relative error in T is given by the formula (in your answer use DeltaT for )

Now we can find the relative error in T2 by multiplying the relative error in T by (Click For List) 1 2 3 pi (From equation 1.8)

We finally need to convert the relative error in T2 in to the absolute error. The formula for the absolute error in T2 is thus:

=

and its numerical value is = [Num] [Units]
