Q 2.26: It is claimed that two caesium clocks if allowed to run for 100 years, free from any disturbance, may differ by only about 0.02 s. What does this imply for the accuracy of the standard caesium clock in measuring a time-interval of 1 s?
In terms of seconds, 100 years =
Given, Difference between the two clocks after 100 years = 0.02 s
In 1 s, the time difference
Accuracy in measuring a time interval of 1 s =
Accuracy of 1 part in
