Question

In an experiment of simple pendulum, the
time-period of 25 oscillations is measured as
50 seconds by a stopwatch of least count
0.2 second. The %age error in the measurement of
time-period of the simple pendulum will be​

Answer 1

Answer:

Explanation:

We have to calculate the max % error in the measurement so, firstly , least count of stop wash = 1/5 or 0.2 as you want to take then , . Given time take =25sec now we know %error =dalta A / A *100 so by doing this we get the value 0.8
