Compressive 18853

The granite cube with an edge length of 1 dm and a weight of 2.5 kg is immersed in a container with water. How much buoyancy makes it lighter? How much compressive force does the cube exert on the bottom of the container?

Correct answer:

F =  10 N
F2 =  15 N

Step-by-step explanation:

a=1 dm m=2.5 kg m2=1 kg g=10 m/s2  V=a3=13=1 dm3 w=1 kg/dm3 m2=w V=1 1=1 kg  F=m2 g=1 10=10 N
F1=m g=2.5 10=25 N F2=F1F=2510=15 N
