There are atomic clocks capable of measuring time with an accuracy of 1 part in . If two such clocks are operated with precision, then after running for 5000 years, these will record
View answer and explanation
Correct option: A
A difference of nearly 1 s
Option A (A difference of nearly 1 s) is correct because it involves calculating the time difference between two atomic clocks with an accuracy of 1 part in after running for 5000 years. The calculation involves converting years to seconds and then finding the maximum possible difference.
