A) 3927 sec
B) 3727 sec
C) 3427 sec
D) 864 sec
Correct Answer: D
Solution :
\[T\propto \sqrt{l}\]Þ \[\frac{\Delta T}{T}=\frac{1}{2}\frac{\Delta l}{l}=\frac{0.02}{2}=0.01\]Þ\[\Delta T=0.01\,T\] Loss of time per day \[=0.01\times 24\times 60\times 60\]\[=864\sec \]You need to login to perform this action.
