If 1 hectare land area of 20 cm soil depth has a bulk density of 1.6 g/cm', what is the average mass of the soil in 1 hectare in kg?​

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
