It is claimed that two cesium 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 cesium clock in measuring a time-interval of 1 s ?
Toppr Errror in 100 years =0.02s Error in 1s= 100×365 4 1 ×24×60×60 0.02 =7.9×10 −13 ≈10 −12 Hence, the accuracy of standard caesium clock in measuring a time interval of 1s is 10 −12
