Solution
The correct option is A12m The reason why we come down when jumping is the gravitational pull. Let's imagine that F force was required for us to jump 2m with g gravitational force. Mathematically,
g generates 2m of height in jump.
We know, P.E∝gh (as potential energy=mgh and mass and energy will be constant)
When g changes to g6, the potential energy will still be the same.
