A body falls from a height $h = 200\,m$ (at New Delhi). The ratio of distance travelled in each $2\, sec$ during $t = 0$ to $t = 6$ second of the journey is

A

$1:4:9$

B

$1:2:4$

C

$1:3:5$

D

$1:2:3$

Solution

(c) ${S_n} \propto (2n – 1)$.

In equal time interval of $2$ seconds

Ratio of distance $ = \;1:3:5$
