1.5\,\text{kg}

object of volume

1.0\times10^{-4}\,\text{m}^3

is fully submerged in water and suspended from a spring balance inside an elevator that is moving upward with an acceleration of

2\,\text{m s}^{-2}

. Take

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

and

g = 10\,\text{m s}^{-2}

. What will be the reading on the spring balance? (a)

17.0\,\text{N}

(b)

18.0\,\text{N}

(c)

16.8\,\text{N}

(d)

11.2\,\text{N}
