The Total solution for NCERT class 6-12
It is claimed that two cesium clocks, if allowed to run for 100years, free from any disturbance, may differ by only about 0.02 s. What doesthis imply for the accuracy of the standard cesium clock in measuring atime-interval of 1 s?
Difference in time of caesium clocks = 0.02 s
Time required for this difference = 100 years
= 100 ├Ч 365 ├Ч 24 ├Ч 60 ├Ч 60 = 3.15 ├Ч 109┬аs
In 3.15 ├Ч 109┬аs, the caesium clock shows a timedifference of 0.02 s.
