(i) Velocity of A displaced = 6.0 x 12 cm3
Mass of A displaced = density x volume = 12 x 10-6 x 800 = 0.0096 kg
Weight of A displaced = mass x gravity = 0.0096 x 10 = 0.096 N
(ii) Volume of B displaced = 6.0 x 3 = 18 cm3
Weight of B displaced = v x density x gravity
= 18 x 10-6 x 1000 x 10 = 0.18 N
