The frequency of vibration of string is given by \[\nu =\frac{p}{2l}{{\left[ \frac{F}{m} \right]}^{1/2}}\]. Here p is number of segments in the string and l is the length. The dimensional formula for m will be [BHU 2004]

• A.             \[[{{M}^{0}}L{{T}^{-1}}]\]
• B.                      \[[M{{L}^{0}}{{T}^{-1}}]\]
• C.             \[[M{{L}^{-1}}{{T}^{0}}]\]
• D.                      \[[{{M}^{0}}{{L}^{0}}{{T}^{0}}]\]
