Time taken by an object falling from rest to cover the height of \( h_{1} \) and \( h_{2} \) is respectively \( t_{1} \) and \( t_{2} \) then the ratio of \( t_{1} \) to \( t_{2} \) is
[RPMT 1999; RPET 2002]
(a) \( h_{1}: h_{2} \)
(b) \( \sqrt{h_{1}}: \sqrt{h_{2}} \)
(c) \( h_{1}: 2 h_{2} \)
(d) \( 2 h_{1}: h_{2} \)
