Three blocks have the same volume. Block #1 floats 50% submerged. It has a weight of 1 N. The two others sink, so they are suspended by cables. Block #2 experiences a 1-N tension force and block #3 a 2-N tension force. Calculate the weight of block #2 and block #3.
weight of block 2=2+1N
block3=2+3 N
hint: if half block 1 is submerged, and it has a total weight of 1 N, then half the block displaces 1N, and the entire block displaces 2 N
