Question

if a leaf from an exercise book and a coin are released from a height of 6feet at the same time, which one of the two will reach the ground first? explain the reason. ​

Answer 1

Answer:

case 1st #when we negalet air and atomsphere

then leaf and coin will reach ground simultaneously becoz atraction due to gravity is same

ie force pulling then down is same

how you aske so here a mathamatical proof

as we know

$F = \frac{Gm1m2}{ {r}^{2} } \\ \\ also \: we \: know \: that \: \\ \\ F = ma \: \\ \\ here \: m \: is \: mass \: of \: object \: \\ \\ so \: ma = \frac{Gm1m2}{ {r}^{2} } \ \: (in \: this \: equation \: m1 \: is \: mass \: of \: earth \: and \: m2 \: is \: mass \: \: of \: object \: ) \\ \\ now \: a = \frac{Gm1}{ {r}^{2} }(coz \: m \: will \: divide \: m2 \: coz \: they \: are \: \: same \: ) \\ \\ hence \: proved \: that \: acceletion \: due \: to \: gravity \: does \: not \: depend \: uopn \: mass \:$

case 2 # if atomsphere is not neglected

then coin will fall first coz it's heavy thus wind can stop it much but left will be blown away coz it's very light

hope it helps you
