Question
Two clocks A and B are being tested against a stranded clock located in the national laboratory At 10 : 00 AM by the standard clock, the reading of the two clocks are shown in following table
If you are doing an experiment that requires precision time interval measurements, which of the two clocks will you prefer?
If you are doing an experiment that requires precision time interval measurements, which of the two clocks will you prefer?
Options
A.clock A
B.clock B
C.either clock A or clock B
D.Neither clock A nor clock B
Solution
The average reading of clock A is, closure to the standard time and the variation in time is smaller for clock B. As clock’s is zero error is not significant for precision work because a zero error can easily corrected. Hence clock B to be preferred.
