Water, dripping at a constant rate from a faucet, falls to the ground. At any instant there are many drops in the air between the faucet and the ground. Where does the center of mass of the drops lie relative to the halfway point between the faucet and the ground? (a) Above it (b) Below it (c) Exactly at the halfway point
When I looked at this, I thought the answer is (b) below it since if the water drop and the ground are in a system, then the center of mass will be nearer to the heavier object, which is the ground. But when I looked up the answer it was (a) above it. Could you please explain why? Thank you!
