Answer:
Both the objects reach the ground at the same time
Explanation:
When the objects are dropped, force of gravity acts on them.
Force acting on mass "M" = Mg &
Force acting on mass "m" = mg
(where "g" is acceleration due to gravity)
We know that Acceleration = Force/mass
Hence Acceleration of mass M =Mg/M
= g
And acceleration of mass m = mg/m
=g
As we see that both the bodies have same acceleration, they reach the ground at the same time.
