A string of uniform thickness and length \(\text { I }\) is subjected to a tensile force F. It vibrates with frequency \(\boldsymbol{v}\) in p segments such that the relation \(v=\frac{p}{21}\left(\frac{F}{m}\right)^{\frac{1}{2}}\) holds good. If p is a number and \(\boldsymbol{v}\) is frequency, then the dimensional formula of m is
- M
- ML-1T0
- \(\text { MLT }\)
- \(\mathrm{ML}^{-3} \mathrm{~T}^{-4}\)
Answer
(B) ML -1 T 0
