@@itsbro9527 💪💪yes will be more consistent from now on

Hi, thanks for pointing that out. I will be more careful next time. The final answer should still be correct I believe.

omg im sorry, i realise u converted 15 cm to m, sorry

Hi @milanbasu3894 thank you for the comment. Using conservation of energy is definitely much easier than what I did. I guess using kinematics is just another way approach to this problem if you dont want to deal with using energy.

Thanks for liking

thank you very much 😊

Hello @harinesh1454. If Moon's diameter is 4 times smaller than Earth's diameter, then the Moon's radius will also be 4 times smaller than Earth's radius. For example: If Earths diameter is 8, then Earth's radius is 8/2 = 4. Since Moon's diameter is 4 times smaller than Earth's then the moon's diameter would 8/4 = 2. So the moon's radius will be 2/2 = 1. Even if we were to work with diameter for the question, we would still get the write answer. instead r for the moon we would write De/8 and instead of r for earth we would write de/2. Solving with these values gets you the same 2/9 answer at the end.

Coming very soon!
