A block of material of specific gravity 0.4 is held submerged at a depth of 1m in a vessel filled with water. The vessel is accelerated upwards with acceleration of `a_(o) = g//5`. If the block is released at t = 0, neglecting viscous effects, it will reach the water surface at t equal to `(g = 10 m/s^(2))` :

A small block of wood of specific gravity 0.5 is subnerged at a depth of 1.2 m in a vessel filled with water. The vessel is accelerated upwards with an acceleration a_(0) = (g)/(2) . Time taken by the block to reach the surface, if it is released with zero initial velocity is (g = 10 m//s^(2))

A small block of wood, of specific gravity 0.4 is submerged in water at a depth of 2.9 m. If the block is released from rest. Then choose the correct alternative(s).

A small block of wood of relative density 0.5 is submerged in water at a depth of 5 m When the block is released it starts moving upwards, the acceleration of the block is (g=10ms^(-2) )
