Question

in the experiment of simple pendulum error in length of pendulum (l) is 5% and that of g is 3% then find percentage error in measurement of periodic time for pendulum

Answer 1

Answer:

4 sec

Explanation:

as we know that the formula of Time period is; T=2π√l/g

in this way to calculate %error then

∆T/T*100%=Sqrt(∆l/l+∆g/g)*100%=

5/2+3/2=4
