T=2pie √l/g this is the required expression
tinaghosh:
that is the case for a pendulum
Ok then learn by urself
when you don't know the correct answer plz don't attempt to answer it just for gaining points.... anyways thanks for your help
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 ..

Correct formula is 1/2 underoot T/ML
thank you so much @ritikaalmadi thanks a lot
My pleasure
