\displaystyle t = \sqrt{\dfrac{2g}{h}}\implies t\;\alpha \;\dfrac{1}{\sqrt{h}}\\\\\displaystyle \dfrac{t_1}{t_2} =\sqrt{\dfrac{h_2}{h_1}}\implies\dfrac{h_1}{h_2} =\left(\dfrac{t_2}{t_1}\right)^2 =\left(\dfrac{2}{1}\right)^2=4

Answer:

\frac{f^1}{f^2} =  \frac{3}{4}

Explanation:

Solution :

s = ut + \frac{1}{2} gt.^{2} when u = 0 , s=\frac{1}{2} gt.^{2} i.e,. st^{2}

\frac{h^{1} }{h^{2} } =(\frac{t^{1} }{t^{2} } ) ^{1} = (\frac{1}{2} )^{2} = \frac{1}{4}

( b ) \frac{h^{1}}{h^{2}} = \frac{t^1}{t^2_{2} }  = \frac{9}{4}\frac{f^1}{f^2} =  \frac{3}{4}
