Answer:
So height on moon = 2 × height on mars
So option (a) will be correct answer
Step-by-step explanation:
We have given the


We know that energy of any object is always conserved
Let the object is falling downward, when the object heats the ground its kinetic energy will be changed in potential energy
Let

So


For moon

We have given that speed is same on both mars and moon
So





So height on moon = 2 × height on mars
So option (a) will be correct answer
