20\,\text{g}

plastic bead (density

800\,\text{kg}\,\text{m}^{-3}

) is released in water inside a tank that is accelerating downward at

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

. Determine the magnitude and direction of the bead’s acceleration relative to the tank immediately after release. Ignore viscous drag.
