A block of material of volume 20cm^-3 and density 2.5gcm^-3 is suspended from a spring balance with half the volume immersed in water. What is the reading of the spring balance? (Density of water = 1.0gcm^-3).

mass of block=vd
=20*2.5=50g
mass of water=vd
vol of water displaced= 10 since half of the volume of of block is immersed
d=1
mass of water=1*10=10g
reading of bal=50g-10g= 40g

Wblock=pv/100


spring balance scale is 100
Wwater=pv/2

half of volume

total =Wb-Ww

it will be in Newtons


to convert it to kg
multiple by 1000
