Question
When a golf ball is lowered into a measuring cylinder containing water, the water level rises by 3cm3 when the ball is completely submerged. If the mass of ball in air is 33g, find its density.
✓
Answer
Volume of golf ball = rise in water level = 30 cm3
Density of ball $=\frac{\text{Mass of ball}}{\text{Volume of ball}}=\frac{33}{30}=1.1\text{g}/\text{cm}^3$
Density of ball $=\frac{\text{Mass of ball}}{\text{Volume of ball}}=\frac{33}{30}=1.1\text{g}/\text{cm}^3$
