Question

A stop clock gives 50 ticks in 25 secinds. What is the maximum uncertainty in the reading of a time interval measure with this click disregarding reaction error?what is the limit of uncertainty?

Answer 1

Stop clock have least count of 1 second so, the maximum uncertainty in the reading of a time interval measured with this clock is 1 sec.

The limits of uncertainity is

$$[25-0.5;25+0.5]=[24.5;25.5]$$
