    Magnitude of force F experienced by a certain object moving with speed \[\upsilon \] is given by \[F=K{{\upsilon }^{2}}\], where \[K\] is a constant. Find the dimensions of \[K\].

    Answer:

                    \[[K]=\frac{[F]}{[{{\upsilon }^{2}}]}=\frac{[ML{{T}^{-2}}]}{{{[L{{T}^{-1}}]}^{2}}}=\mathbf{[M}{{\mathbf{L}}^{\mathbf{-1}}}\mathbf{]}\]
