A ball is released from the top of a tower. The ratio of work done by force of gravity in first, second and third second of the motion of the ball is
$1:2:3$
$1:4:9$
$1:3:5$
$1:5:3$
A ball is released from the top of a tower. The ratio of work done by force of gravity in first, second and third second of the motion of the ball is
When the ball is released from the top of tower then ratio of distances covered by the ball in first, second and third second
${h_I}:{h_{II}}:{h_{III}} = 1:3:5:$[because ${h_n} \propto (2n - 1)]$
Ratio of work done $mg{h_I}:mg{h_{II}}:mg{h_{III}}$$= 1:3:5$
