T=2pie √l/g this is the required expression


tinaghosh: that is the case for a pendulum

tinaghosh: when you don't know the correct answer plz don't attempt to answer it just for gaining points.... anyways thanks for your help
ritikaalmadi: The frequency of vibration may depend upon length of the string (L), tension(F) and mass per unit length(m=M/L).
Let
u α LaFbmcor u =k LaFbmc−−−(i)Writing dimensions, we get[M0L0T−1]=La(M1L1T−2)b(ML−1)c=Mb+cLa+b−cT−2bHere,b+c=0a+b−c=0−2b=−1On solving,a=−1,b=1/2 and c=−1/2Putting these values in (i)u=kL−1F1/2m−1/2=k1LFm‾‾√=k1LF(M/L)‾‾‾‾‾√=kFML‾‾‾√Experimentally, k=1/2So,u=12 ..
ritikaalmadi: Correct formula is 1/2 underoot T/ML
tinaghosh: thank you so much @ritikaalmadi thanks a lot
ritikaalmadi: My pleasure
