A rectangular block of wood of density `800kgm^(-3)` having a mass of 2 kg is pushed in to water so that it is completely submerged and then released. Neglecting viscous forces, the initial acceleration of the block will be `(g=10(m)/(s^(2)))`

Options

A. `1.25(m)/(s^(2))` downward
B. `2.5(m)/(s^(2))` upwards
C. `1.25(m)/(s^(2))` upward
D. `2.5(m)/(s^(2))` downward

Explanation

`a_("net")=("force of buoyancy-weight of wooden block")/("mass of the body")`
`a=(F_(b)-W)/(m)=(Vd_(W)-Vd_(B)g)/(Vd_(B))`
