Hey mate,
◆ Proof -
# Given-
m1 = 2 kg
m2 = 4 kg
# Solution-
When a ball is dropped from height h,
s = ut + 1/2 at^2
Here, s = h, u = 0 & a = g, hence-
h = 1/2 gt^2
t = √(2h/g)
Both balls are dropped from same height and are under same gravitational acceleration.
As time to reach earth is independent of mass of ball, both will reach earth simultaneously.
Hope this helps you...
