Question

if two objects is thrown from a gravity free space (where m1 > m2) which object will reach the ground the fastest?​

Answer 1

The force of the object downwards or the weight is mass times acceleration due to gravity, or mg

Now the net gravitational force between to particles, here the earth and the object is given by the equation:

F=(G∗M∗m)/R2

where M is the mass of earth, R the radius of earth and G the universal gravitational constant with a value of about 6.67 *10^(-11) .

Equating the weight of the object and the net force, we get

mg=(G∗M∗m)/R2

m gets cancelled out on both sides. Hence,

g=(G∗M)/R2

So g doesn't depend on the mass of the object m .

So the acceleration is constant for all objects.

Hope this helps.

Answer 2

Explanation:

both will reach at the same time
