A man of 50 kg mass in standing in a gravity free space at a height of 10m above the floor. He throws a stone of 0.5 kg mass downwards with a speed of 2m/s. When the stone reaches the floor, the distance of the man above the floor will be

View answer and explanation

Correct option: C

10.1 m

Option C (10.1 m) is correct because the man moves upward due to conservation of momentum when he throws the stone downwards.
