Two clocks are being tsted against a standard clock located in the national laboratory. At `10: 00: 00` AM by the standard clock, the readings of the clocks are :

If you are doing an experiment that requires prescision time interval measurements, which of the two clock will you prefer ?
(a) Clock A
(b) Clock B
(c) Either Clock A or B
(d) Neithr A nor B

Text Solution

Verified by Experts

The average reading of Clock A is much closure to the standard time than the average reading of clock B and the range of vibration over the 5 days of observation is much smaller for clock B. As here clock's zero error is not significant for precision work, because a zero error can always be easily corrected. Hence, clock B is to be preferred to clock A.
