Let us now use a millimeter scale (on which millimeter marks are there). This is also our normal meter scale which we use in our routine life. From the figure, we can see that length AB is more than 3.3 cm and less than 3.4 cm. If we note down the length, l= AB = 3.4cm. Then, this measurement has two significant figures 3 and 4 in which 3 is absolutely correct and 4 is reasonably correct (doubtful). Least count of this scale is 0.1 cm because this scale can measure accurately only upto 0.1 cm. Further, maximum uncertainly or maximum possible error in l can also be 0.1 cm.

Let us use a centimeter scale (on which only centimeter scales are there) to measure a length AB. From the figure, we can see that length AB is more than 7 cm and less than 8cm . In this case, Least Count (LC) of this centimeter scale is 1 cm, as it can measure accurately, upto centimeters only. If we note down the length (l) of line AB as l = 7cm then maximum uncertainly or maximum possible error in l can be 1 cm(=LC), because this scale can measure accurately only upto 1cm.

In a simple pendulum experiment, the length of the thread is measured as 102.3 cm and the diameter of the bob as 2.24 cm. What is the maximum possible error in the value of the effective length of the pendulum?

The error in the measurement of length (L) of time simple pendulum is 0.1% and the error in the period (T) is 3%. The maximum possible error in the measurement of (L)/(T^(2)) is
