Problem

A stone is weighed with a spring balance and its weight in air is found to be

2.45\,\text{N}

. Taking

g=9.8\,\text{m/s}^2

, the stone is then fully immersed in a measuring cylinder; the water level rises from

30\,\text{mL}

53\,\text{mL}

. What is the density of the stone (nearest

100\,\text{kg/m}^3

)? a)

9800\,\text{kg/m}^3

12500\,\text{kg/m}^3

10900\,\text{kg/m}^3

8600\,\text{kg/m}^3
