The reading on a spring balance is 7.2N when a metal ball bearing is hung from its lower end in air the density of the metal is 9.00g/cm^-3 and that of water is 1.00g/cm^-3.The ball is immersed in water in a Eureka can until it is completely submerged.
i) What is the volume in m³ of water displaced.
ii) What is the reading of the spring balance in N when the ball is completely submerged in water.

= 8.0 x 10^-1N
Reading on spring balance
7.2N – 0.8 N
= 6.4N
