प्रश्न
When a golf ball is lowered into a measuring cylinder containing water, the water level rises by 30 cm3 when the ball is completely submerged. If the mass of ball in air is 33 g, find its density.
उत्तर
ρ (density of golf ball) = ?
V (volume of steel piece) = 30 cm3
m (mass of steel piece) = 33 g
`ρ = m/V`
= `33/30`
`ρ = 1.1 "g/cm"^3`
Ans: Density of the golf ball = 1.1 g/cm3.
