So I came across a question on the internet and its confused me a lot.
We have 200g of water inside a cup. We neglect the mass of the cup completely and assume no water is lost. We also assume that the gravitational field is uniform within our experiment room.
So we place the cup on some scales and it weighs 1.962N. (0.2 * 9.81).
Now we have a 10g mass object which comes in two different volumes. One volume is such that the object sinks. The other volume is such that the object floats.
So the question was asked whether the scales would record different weights for the case where the object sank and the case where the object floats.
Now the reply for the question given was that the weight (the one measured by the scales) would stay the same, regardless. But I've seen other replies on the internet that start talking about "apparent" weight etc etc and getting confused..
