0.5 Sec would be the least count.
Explanation:
Given that,
Range of stopwatch = 5 s
Total division of stopwatch = 10
As we know that,
The least count is described as the smallest value of measurement that can be measured by using an instrument.
∵ Least count of stopwatch = Range of instrument / Total divisions
L.C = 5/10=0.5s
