Problem

A stone of mass

0.8\,\text{kg}

is gently placed on the bottom of a tank full of water. Its volume is

3.0 \times 10^{-4}\,\text{m}^3

. Calculate the magnitude of the normal reaction exerted by the tank bottom on the stone. (Take

\rho_{\text{water}} = 1000\,\text{kg m}^{-3}

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

)
