એક બળને \(\mathrm{F}=\mathrm{ax}^2+\mathrm{bt}^{1 / 2}\) વડે દર્શાવેલ છે. જયાં, \(\mathrm{x}=\) અંતર અને \(\mathrm{t}=\) સમય છે. તો \(\mathrm{b}^2 / \mathrm{a}\) ના પરિમાણો _______ છે.

\({[\mathrm{a}]=\frac{[\mathrm{F}]}{\left[\mathrm{x}^2\right]}=\left[\mathrm{M}^1 \mathrm{~L}^{-1} \mathrm{~T}^{-2}\right]}\)

\({[\mathrm{b}]=\frac{[\mathrm{F}]}{\left[\mathrm{t}^{1 / 2}\right]}=\left[\mathrm{M}^1 \mathrm{~L}^1 \mathrm{~T}^{-5 / 2}\right]}\)

\({\left[\frac{\mathrm{b}^2}{\mathrm{a}}\right]=\frac{\left[\mathrm{M}^2 \mathrm{~L}^2 \mathrm{~T}^{-5}\right]}{\left[\mathrm{M}^1 \mathrm{~L}^{-1} \mathrm{~T}^{-2}\right]}=\left[\mathrm{M}^1 \mathrm{~L}^3 \mathrm{~T}^{-3}\right]}\)
