The mean value of period of oscillation ...

The mean value of period of oscillation of a simple pendulum in an expreiment is 2.825 s. The arithmetic mean of all the absolute errors is 0.11 s. Round off the period of simple pendulum to approximate number of significant figures. Given resson.

Text Solution

Verified by Experts

As mean absoulte error is 0.11 s -has two
significant digits, therefore mean value of time
period should also have two significant digits
i.e., T =2.8s.
