Question

m A cublical block of mass 10 kg
and density 800 kg/m3 A | | ( (al find the creight of water displacement by the block (6) Find the volume of block & submerged
​

Answer 1

Answer:

Here we have to use the concept of buoyancy force.

Buoyancy force = (Volume submerged)(density of liquid)(g)

Force of buoyancy will act upwards on the body

Volume=

density

By Newton's Second Law,

mg−Vρg=ma

⇒2×10−

×1000×10=2a

a=−2.5ms

−2

So the net acceleration is 2.5ms
