'2 balls of mass ratios 1:2 are dropped from the same height. State the ratio between their velocities when they strike the ground, the ratio of forces acting on them during motion.'

Answer 1

Didn't Galeilo demonstrate the hit the ground at the same time, with the same velocity?

Forces? it is gravity, so the ratio is 1:2

Fb=K mass/height^2 where height is the distance frm the ball to center of Earth.
