The velocity vv of a particle is given by v=Fμv = \sqrt{\frac{F}{\mu}}, where FF is force and μ\mu is linear mass density (mass per unit length). The dimensions of μ\mu are: (A) [ML−1][ML^{-1}] (B) [ML−2][ML^{-2}] (C) [MT−2][MT^{-2}] (D) [M−1L][M^{-1}L] (A) [ML−1][ML^{-1}] (B) [ML−2][ML^{-2}] (C) [MT−2][MT^{-2}] (D) [M−1L][M^{-1}L]
